In 2013, West Bend Mutual Insurance Co. (“West Bend”) brought this legal malpractice action against its former counsel, Paul Schumacher, and his law firm, Roddy, Leahy, Guill & Ziema, Ltd. (“RLGZ”). The gravamen of the complaint is Mr. Schu-macher’s alleged performance in defending a workers’ compensation claim in 2005 and 2006. The district court dismissed the second amended complaint on the defendant’s 12(b)(6) motion and terminated the case. In the district court’s view, the complaint failed to set forth with sufficient specificity a cause of action for legal malpractice. We agree; the complaint fails to state plausibly the causation and harm elements required under Illinois legal malpractice law. Accordingly, we affirm the judgment of the district court.
I
BACKGROUND
West Bend first filed a legal malpractice action based on the performance of Mr. Schumacher and RLGZ in the underlying workers’ compensation matter in 2008. The parties later agreed to a dismissal of that claim and entered into a tolling agreement pending the resolution of several other tangentially related actions, including one for medical malpractice.
Following the resolution of those claims, West Bend brought the present action in *673the United States District Court for the Northern District of Illinois in July 2013, and filed an amended complaint in December 2013. After each of these filings, the defendants moved to dismiss. The district court granted each of the, motions, concluding that the allegations were too speculative or vague. In each case, however, the court also granted leave to amend.
A.
The allegations of the Second Amended Complaint are central to our task. We therefore begin with a rendition of its contents.
In December 2005, West Bend retained RLGZ to provide legal representation with respect to a workers’ compensation claim filed by John Marzano against West Bend’s insured, Nelson Insulation. The substance of Marzano’s claim is not described. Mr. Schumacher was the attorney with principal responsibility for defending against the Marzano claim. After several continuances, including one requested by Mr. Schumacher, the Illinois Workers’ Compensation Commission (“IWCC”) scheduled a hearing on the matter for August 23, 2006.
According to the complaint, Marzano supported his claim with the deposition of his treating physician, Dr. Sheinkop. He also had undergone an independent medical examination by Dr. Nelson, who provided a written report. This report indicated that Dr. Nelson’s testimony would be favorable to West Bend and would counter Dr. Sheinkop’s opinion. In his preparation for the scheduled August hearing, Mr. Schumacher did not speak to or depose Dr. Nelson. Instead, without seeking the approval of West Bend, he agreed with Marzano’s counsel to put a redacted version of Dr. Nelson’s report in evidence. Mr. Schumacher also did not speak to any other witnesses or potential witnesses until the day before the scheduled hearing; he then learned that a witness with relevant testimony was out of town and would not be available to testify the following day.
Prior to the hearing, Mr. Schumacher possessed other information .that was beneficial to West Bend’s .defense, including that Marzano worked a full day on the day of the alleged incident, that he continued to work for two additional weeks until he was laid off, and that his own' treating physician could not find any change in the condition of his knee following theincidént. Mr. Schumacher disclosed all of this information, favorable to his client, to Marza-no’s counsel prior to the hearing.
Documents also indicated that Marzano had not reported the incident until after he was laid off and had retained an attorney. But Mr. Schumacher did not investigate Marzano’s contrary statements and did not verify them with Marzano’s former supervisor, to whom the incident report allegedly had been made.
On, the day of the IWCC hearing, Mr. Schumacher did not request a continuance or a bifurcated proceeding to allow for the presentation of additional evidence. Instead, “without [West BendJ’s knowledge or agreement,” Mr. “Schumacher made the representation to counsel for [Marzano] that [West Bend] would accept liability of the workers’ compensation claim”1 and the arbitrator was “advised of that position.”2 West Bend claims that it “was forced to accept that agreement pending further investigation of other litigation options.”3
*674The complaint further alleges that, as a result of Mr. “Schumacher’s unauthorized actions and representations to [West Bend], [West Bend] was forced to. make significant payments, including temporary total disability [(“TTD”)] benefits and medical-expenses, with little or no likelihood of recovery.”4 To “justify his concession of compensability, defendant Schu-macher overemphasized” to his client “the potential for penalties to [West Bend] if the hearing had gone forward.”5 Mr. Schu-macher “continued to counsel [West Bend] against getting the case reopened to present its defenses as. he believed the case was indefensible.”6
According to the complaint, West Bend alleged that Mr. Schumacher breached duties to. West Bend by virtue of “(a) his unauthorized stipulation concerning com-pensability; (b) his failure to adequately investigate the claim or claimant’s preexi[s]ting medical condition; (c) his subsequent representations to [West Bend] regarding their litigation options!;] and (d) his failure to adequately advise [West Bend] of material facts and legal options prior to hearing.”7 The specific allegations also concerned Mr. Schumacher’s failure to depose Dr. Nelson, his disclosure to Mar-zano’s counsel of information beneficial to West Bend, and his failure to discover and remedy the unavailability of a relevant witness for the hearing.
All of these, West Bend alleged, resulted in its being “forced to accept a disadvantageous position which greatly compromised its ability to defend the claim.”8 It also was “forced to pay additional sums and eventually chose to reach a disputed settlement in order to mitigate its exposure”:
[although [West Bend] technically had the option of contesting the compensa-bility of the claim or filing a motion to terminate benefits after retaining new counsel, those options were not practical as plaintiff had been paying benefits for some time and the Commission was unlikely to und[o] or reverse such payments. In other words, [West Bend]’s payment of benefits up to that point severely prejudiced its capability to reverse the concession by defendant Schu-macher.[9]
’ The complaint further alleged that even if the Commission had determined that West Bend was not liable, it was “extremely unlikely” that it would require repayment of prior benefits, and, if it did, “collection of those funds would have been difficult if not impossible.”10
B.
In its July 18, 2014 order' granting the motion to dismiss the Second Amended Complaint, the district court determined that, with respect to the bulk of West Bend’s allegations about Mr. Schumacher’s performance—including the failure to depose Dr. Nelson, the failure to contact witnesses prior to the hearing, and the disclosure of certain facts to Marzano’s counsel—West Bend’s complaint “does not ... explain how any of these alleged acts and omissions harmed' its defense.”11 With respect to the allegation that Mr. Schu-macher had represented that West Bend *675would accept liability, the district court stated:
Though Plaintiff alleges that the representation “forced [it] to ... pay[ ] ... temporary total disability benefits and medical expenses, with little or no likelihood of recovery” and “to reach a disputed settlement in order to mitigate its exposure”, these assertions, are legally and factually unsupported. As a matter of law, paying benefits pending resolution of a claim does not preclude an employer from contesting liability. Moreover, plaintiff admits that it could have contested the claim, despite the representation. In short, because plaintiff does not and cannot allege that defendants’ representation was the cause of any damages it may have suffered, the representation cannot support a malpractice claim.[12]
The court therefore granted the motion, and, because it had concluded that West Bend had failed to state a claim in three successive complaints, it terminated the case.
West Bend now appeals.

DISCUSSION
A.
We begin by setting out the principles that must govern our assessment of the Second Amended Complaint.'
1.
We review a district court’s dismissal under Rule 12(b)(6) de novo. Bible v. United Student Aid Funds, Inc., 799 F.3d 633, 639 (7th Cir. 2015). We, like the district court, must “accept as true all factual allegations in the amended com.plaint- and draw all permissible inferences in [the plaintiffj’s favor.” Id.- A complaint will survive a 12(b)(6) motion if, after the court disregards any portions that are “no more than conclusions,” it “contain[s] sufficient factual matter, accepted as true, to Estate a claim to relief that is plausible on its face.’ ” Ashcroft v. Iqbal, 556 U.S. 662, 678-79, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007)). “A claim has facial plausibility when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Id. at 678, 129 S.Ct. 1937. “ ‘-Plausibility’ is not a synonym for ‘probability’ in this context, but it asks for ‘more than a sheer possibility that a defendant has acted unlawfully.’ ” Bible, 799 F.3d at 639 (quoting Olson v. Champaign Cty., 784 F.3d 1093, 1099 (7th Cir. 2015)). After Twombly and Iqbal, a plaintiff seeking to survive a motion to dismiss must “plead some facts that suggest a right to relief that is beyond the speculative level.” In re marchFIRST Inc., 589 F.3d 901, 905 (7th Cir. 2009) (internal quotation marks omitted). That is, “[w]hile a plaintiff -need not plead detailed factual allegations to survive a motion to dismiss, she still must provide more than mere labels and conclusions or a formulaic recitation of the elements of a cause of action for her complaint to be considered adequate.” Bell v. City of Chicago, 835 F.3d 736, 738 (7th Cir. 2016) (internal quotation marks omitted).
We .have interpreted the standard announced by the Supreme Court as requiring that “the plaintiff ... give enough details about the subject-matter of the case to present a story that holds together. In other words, the court will ask *676itself could these things have happened, not did they happen.” Swanson v. Citibank, N.A., 614 F.3d 400, 404 (7th Cir. 2010) (emphasis in original). In the end, “the plausibility determination is -⅛ context-specific task that requires the reviewing court to draw on its judicial .experience and common sense.’ ” McCauley v. City of Chicago, 671 F.3d 611, 616 (7th Cir. 2011) (quoting Iqbal, 556 U.S. at 679, 129 S.Ct. 1937).
2.
Because federal jurisdiction over this action is premised on diversity of citizenship, see 28 U.S.C. § 1332, we must look to the law of the state in which the district court sits to determine the applicable governing law. Erie R.R. Co. v. Tompkins, 304 U.S. 64, 79-80, 58 S.Ct. 817, 82 L.Ed. 1188 (1938), The parties agree that Illinois law governs the elements of this legal malpractice action. The Supreme Court of Illinois has stated succinctly that a cause of action for legal malpractice includes the following elements: (1) the existence of an attorney-client relationship that establishes a duty on. the part of the attorney, (2) a negligent act or omission constituting a breach of that duty, (3) proximate cause of injury, and (4) actual damages. See Sexton v. Smith, 112 ILL.2d 187, 97 Ill.Dec. 411, 492 N.E.2d 1284, 1286-87 (1986).
Illinois courts have described the State’s legal malpractice cause of action as following a case-within-a-case model:
A legal malpractice suit is by its nature dependent upon a predicate lawsuit. Thus, a legal malpractice claim presents a case within a case. [N]o malpractice exists unless counsel’s negligence has resulted in the’loss of an underlying cause of action, or the loss of a meritorious defense if the attorney was defending in the underlying suit.
Nelson v. Quarles & Brady, LLP, 375 Ill.Dec. 561, 997 N.E.2d 872, 880 (Ill. App. Ct. 2013) (alteration in original) (emphasis in original) (citations omitted) (internal quotation marks omitted).13 Therefore, in assessing the sufficiency of a complaint of legal malpractice we must focus on the underlying claim. See Claire Assocs. by Livaditis v. Pontikes, 151 Ill.App.3d 116, 104 Ill.Dec. 526, 502 N.E.2d 1186, 1190 (1986). The plaintiff must set forth a plausible statement not only that a breach of duty occurred but that the breach caused the plaintiff to lose a valid claim or defense in the underlying action and that, absent that loss, the underlying claim “would have been successful.” Fabricare Equip. Credit Corp. v. Bell, Boyd & Lloyd, 328 Ill.App.3d 784, 263 Ill.Dec. 19, 767 N.E.2d 470, 474 (2002).14 “These elements effectively de*677mand that the malpractice plaintiff present two cases, one showing that her attorney-performed negligently, and a second or predicate ‘case within a case’ showing, that she had a meritorious claim [or- defense] that she lost due to her attorney’s negligence.” Mihailovich v. Laatsch, 359 F.3d 892, 904-05 (7th Cir. 2004).
B.
Having stated the principles that govern our inquiry, we now apply these principles to the particular circumstances of this case.
There is no dispute that West Bend has described adequately the duty element in its malpractice claim. Nor is there any disagreement about the adequacy of West Bend’s narrative with respect to the alleged, attorney conduct constituting a breach of that duty. In that respect, West Bend alleges that Mr. Schumacher, having assumed responsibility for the defense of the claim, failed to prepare adequately for the hearing, revealed inappropriately the defense theory of the case to Marzano’s counsel, and then, without authorization, conceded liability for Marzano’s workers’ compensation claim.15
The allegations with respect to causation and damages present, however, significant concerns. At the outset, we note that the treatment by the Second Amended Complaint of the underlying workers’ compensation claim, which, as we have explained, is central to an assessment of causation and damages, is markedly different from the treatment of Mr. Schumacher’s alleged litigation conduct. While the complaint- describes the conduct in some-detail, it describes the underlying workers’ compensation claim in rather summary fashion. Specifically, while the complaint identifies the injured party as John Mar-zano, it tells us nothing about his claimed injury or his claim against his employer. Instead, it summarily states that “[p]rior. to August 2006, there existed certain factual defenses and a medical causation defense to the Marzano claim.”16
West Bend’s brief on appeal invites our attention to paragraph 25 of the Second Amended Complaint as “setfting] forth [its] factual allegations concerning defendants’ breach of duty, proximate cause and damages.”17 That paragraph of the complaint contains an abbreviated description of Mr. Schumacher’s claimed errors, but, with respect to the crucial elements of causation and damages, says only that West Bend “was forced to accept a disadvantageous position which greatly compromised its ability to defend the claim.”18 This same sort of general language appears in paragraph 28; there West Bend refers to a loss of “valuable factual and legal defenses that would have eliminated or substantially reduced any liability of *678[West Bend] to the claimant.”19 These allegations are conclusory assertions and certainly do not set forth a plausible description of a lost defense that, absent Mr. Schumacher’s alleged neglect, would have assured West Bend’s success on the underlying claim. Iqbal, 556 U.S. at 678-79, 129 S.Ct. 1937.
West Bend has not invited our attention to any other factual allegations which'detail the “valuable factual and legal defenses” lost because of Mr. Schumacher’s litigation conduct. In its appellate brief, West Bend does assert that it “is prepared to' offer evidence that, had defendants not committed the breaches from the standard of care, the Marzano claim would likely have gone in an entirely different direction,” and indeed, that “there is a strong likelihood [that] West Bend could have either won the entire case or significantly reduced the amount of money it ultimately paid.”20 But again, even now, it does not tell us what these defenses are or how they would have produced near or total success in workers’ compensation proceedings.21
The complaint’s description of Mr. Schu-macher’s conduct does include an allegation that, prior to the date of the scheduled workers’ compensation hearing,
defendant Schumacher possessed other documentation and information to support a denial of compensabil[i]ty [of the Marzano claim], including: (a) the claimant’s completion of the day’s work on the- day of the alleged incident; (b) the fact that the claimant continued to work following the alleged incident for an .additional two weeks until he was laid off on September 28, 2005; and (c) the fact that the claimant’s own treating physician, Dr. Sheinkop, could not find any change in the condition of his knee after the alleged incident, as it had already been determined that the claimant was in need of knee replacement surgery.[22]
It also asserts that an unspecified “witness with relevant testimony” was not available to testify and complains that Mr. Schu-macher did not request a continuance.23 It continues by faulting Mr. Schumacher for “reveal[ing] all of this documentation and information—all the key theories of [West Bend]’s defense—to counsel for claimant, which severely compromised [West Bend’s] ability to continue to defend the workers’ compensation claim.”24 We are given no description, however, as to whether or how this evidence would have produced a successful outcome for West Bend.
With respect to the allegation that Mr. Schumacher had stipulated improperly to *679the compensability of the claim, West Bend at least makes the allegation that it was required to pay substantial amounts of money because of the stipulation. But it makes no concrete allegation that its final liability in this matter would have been any different if the stipulation had not occurred.
The Second Amended Complaint therefore leaves us to speculate as to whether and how West Bend would have prevailed on the underlying claim in the absence of the missteps of which it now'accuses its former attorney. But, as our colleague in the district court recognized throughout West Bend’s several attempts to improve the complaint, a plaintiff “must plead some facts that suggest a right to relief that is beyond the speculative level.” In re march-FIRST Inc., 589 F.3d at 905 (internal quotation marks omitted). The district court correctly concluded that the allegations that deal with the substance of the underlying compensation claim and defense fall short of that standard because they provide no plausible description as to how the attorney’s negligence, if it occurred, was the cause of harm to West Bend. Even when evaluated as a whole, the complaint fails to describe, in even the most rudimentary of ways, “that but for [Mr. Schumacher’s] negligence, the plaintiff would have been successful in th[e] underlying” workers’ compensation action. Tri-G, Inc. v. Burke, Bosselman & Weaver, 222 Ill.2d 218, 305 Ill.Dec. 584, 856 N.E.2d 389, 395 (2006). West Bend simply has failed to allege plausibly, despite multiple amendments, that it lost actual, specific, meritorious defenses in the Marzano claim because of Mr. Schumacher’s conduct.
Conclusion
The Second Amended Complaint fails to plead adequately a claim for legal malpractice under Illinois law. Specifically, it fails to allege plausibly that the outcome of the underlying action would have been more favorable to West Bend, had it not been for Mr. Schumacher’s alleged litigation conduct. We therefore affirm the judgment of the district court.

. Most cases identify the loss of a meritorious claim or defense as a part of the element of proximate causation. However, some frame it as part of the element of damages. See, e.g., Bartholomew v. Crockett, 131 Ill.App.3d 456, 86 Ill.Dec. 656, 475 N.E.2d 1035, 1041 (1985) (”[D]amage is an element of a professional malpractice claim that is not presumed, [and plaintiff] bears the burden of pleading and proving that damages resulted. This burden entails establishing that ‘but for’ the attorneys’ negligence, the client would have successfully defended or prosecuted the underlying suit.”).

Seiden, 382 Ill.App.3d 288, 320 Ill.Dec. 592, 887 N.E.2d 736, 746 (2008) (noting that, to satisfy the element of proximate causation in a legal malpractice action, "the plaintiff must plead sufficient facts to establish that ‘but for’ the negligence of the attorney, the client would have successfully defended the underlying suit” (emphasis added)); Ignarski v. Norbut, 271 Ill.App.3d 522, 207 Ill.Dec. 829, 648 N.E.2d 285, 289 (1995) (holding that the plaintiff's burden to plead a case within a case was not satisfied where the pleadings did not “plead ultimate facts establishing” its entitlement to relief on its predicate claim).
.The briefs and the oral argument included significant argument about what precisely Mr. Schumacher conceded. West Bend asserts that he conceded liability on the whole claim. The defendants assert that he simply agreed to pay TTD benefits and the question of final liability remained open until 2010. They ask the court to notice the terms of the eventual settlement agreement reached in the case, which state that no admission of liability has been made by the employer. In their view, we can notice this document as a public record and disregard the contrary allegation, despite our general obligation to take the allegations of the complaint as true under Rule 12(b)(6). We decline to resolve this dispute because for the reasons stated below, we find that the claim, even as alleged, is insufficient to survive dismissal.
