SELYA, Senior Circuit Judge.
In this criminal appeal, the defendant challenges both her conviction (on the ground of instructional error) and her sentence (on the ground of a guidelines-related error). After a thorough review of the record and the applicable law, we affirm the defendant’s conviction but vacate her sentence. The tale follows.
We begin with the denouement. In April of 2005, a federal grand jury charged defendant-appellant Altagracia Ramos-Paulino with attempted transport and concealment of illegal aliens, see 8 U.S.C. § 1324(a)(1), and trafficking in false identification documents, see 18 U.S.C. § 1028(a)(2). These charges stemmed from her involvement with Rafael Cintrón-Brea (Cintrón), a defrocked police officer who became a government informant after pleading guilty to an alien-smuggling charge.
*461 The pertinent facts are as follows. The defendant first met Cintron in 2003. While she piously protests that they did not pool their efforts to transport illegal aliens until January of 2005, Cintron says that they collogued together from the start. We need not resolve this conflict; for present purposes, it suffices that, by all accounts, the joint enterprise was velivo-lant no later than January of 2005. An event that is crucial to this appeal occurred at that time: Cintron reassured the defendant that, notwithstanding his earlier arrest (of which she had recently become aware), she would not be brought to book for the criminal activities that the two of them were planning to undertake.
This brings us to the offense conduct. Between January and April of 2005, Cin-tron and the defendant arranged the transport of four illegal aliens. The defendant was the principal contact for the aliens. With the assistance of a man named Domingo, she gathered information about them, collected payments from them, and obtained false identification documents for them. She then transferred the money, the papers, and the aliens to Cintron with directions about which airline tickets should be purchased.
According to the plan, Cintron was to purchase the tickets and escort the aliens through San Juan’s major international airport, bypassing the usual security checkpoints. Cintron, however, was cooperating with the authorities, and the defendant’s activities led only to her arrest. An indictment followed.
Pretrial proceedings were unremarkable. Cintron was the government’s star witness at the trial. At the close of the evidence, the defendant renewed her earlier request for an entrapment instruction, claiming that Cintron’s assurances had induced her to participate in the criminal venture. The district court refused to instruct on entrapment, and the jury found the defendant guilty on all counts.
The district court continued the case for sentencing and ordered the preparation of a presentence investigation report (PSI Report). The court convened the disposition hearing on April 25, 2006. In making its guideline computations, the court adopted a recommendation put forth in the PSI Report and applied a two-level enhancement based on the defendant’s role in the offenses of conviction. See USSG § 3Bl.l(c). The adjusted offense level, when combined with the defendant’s criminal history category, yielded a guideline sentencing range of 15-21 months. The court proceeded to impose a sentence at the top of the range: 21 months. This timely appeal ensued.
The defendant’s claim of instructional error is easily dispatched. She argues that she was entitled to a jury instruction on entrapment because that was her main theory of defense and the record contained adequate evidence to support it. We do not agree.
It is often said that a criminal defendant is entitled to have the jury instructed on her theory of the case. But that aphorism is not a universal truth: to warrant a jury instruction on a specific theory of defense, the evidence adduced at trial, taken in the light most flattering to the accused, must
plausibly
support the theory.
See United States v. Gamache,
Where, as here, a criminal defendant seasonably requests an instruction on a particular theory of the case and the trial court flatly refuses to submit that theory to the jury, our review is plenary.
See United States v. Nishnianidze,
We have had occasion to apply this framework to efforts to deploy an entrapment defense. When that defense is in issue, the test of evidentiary sufficiency has two facets.
See United States v. Capelton,
Here, the claim of inducement rests exclusively on the January 2005 conversation between Cintron and the defendant. As the defendant envisions it, Cintron lured her into committing the crime by assuring her that “nothing could happen to her because he was a Police Officer.” Appellant’s Br. at 11. In our view, however, this solitary piece of evidence leaves the defendant well short of the finish line.
We repeatedly have held that the simple solicitation of a criminal act or the mere provision of an opportunity to engage in one does not meet the threshold requirement for a finding of wrongful inducement.
See, e.g., Capelton,
In this instance, the defendant’s version of her conversation with Cintron is uncon-tradicted. Taking what was said at face value, a finding of inducement simply will not lie. On that basis alone, the district court’s unwillingness to instruct on entrapment was entirely appropriate. 1
We turn next to the defendant’s claim of sentencing error. The Supreme

Court’s landmark decision in
United States v. Booker,
We review a sentencing court’s findings of fact for clear error.
See United States v. Misla-Aldarondo,
In the case at hand, the defendant makes a rifle-shot objection to one part of the lower court’s sentencing algorithm. This objection takes dead aim at the court’s embrace of a two-level upward adjustment for role in the offense recommended in the PSI Report. The operative guideline provision applies to a defendant who is shown by a preponderance of the evidence to be an “organizer, leader, manager, or supervisor” of between one and five other participants in the crime of conviction. USSG § 3Bl.l(c);
see United States v. Tejada-Beltran,
The defendant’s argument centers on the paucity of evidence that she organized, led, managed, or supervised any other participant in the criminal enterprise. Because the district court did not base the enhancement on specific findings as to whom the defendant may have organized, led, managed, or supervised, we have searched the record (including the PSI Report) in an endeavor to identify any such underlings.
We have come up dry. The district court indicated at one point its belief that the defendant oversaw Cintron. Even if that were true—and the record is murky on the point—such a finding could not sustain the enhancement. For purposes of the “participant” requirement of section 3Bl.l(c), Cintron (who was acting undercover in 2005 as part of a government sting operation) does not count. Neither a government agent nor anyone acting under the direction of a government agent qualifies as a “participant” for purposes of a role-in-the-offense enhancement.
See
USSG § 3B1.1 cmt. n. 1;
see, e.g., United States v. Andreas,
*464 Beyond the defendant’s relationship with Cintron and her dealings with the aliens themselves, there is little if any evidence indicating that she organized, led, managed, or supervised any other participant. Although she worked hand in glove with the mysterious Domingo, there is nothing to show either that he was her subordinate in the chain of command or that she oversaw his activities.
The absence of any such evidence is puzzling, but the record contains a likely explanation. In fashioning the managerial role enhancement, the district court seems to have gone in a different direction. For aught that appears, the court based the enhancement primarily on the defendant’s control over the activities of the criminal enterprise rather than over any 'participants in it.
To justify this focus, the court pointed to language in the guidelines discussing “a defendant who did not organize, lead, manage, or supervise another participant, but who nevertheless exercised management responsibility over the property, assets, or activities of a criminal organization.” USSG § 3B1.1 cmt. n. 2. That description, the court said, “fit[] very well to this defendant’s role.” Elaborating, the court observed that the defendant was the principal contact for the smuggled aliens, that she was apparently responsible for determining fees and accepting payments, that she procured the false identification documents, and that she had some influence over the scheduling of the transports.
We appreciate the district court’s concern. The problem with this approach, however, is that the very application note cited by the court makes it pellucid that the management of criminal activities (as opposed to the management of criminal actors) may ground an upward departure but not an upward role-in-the-offense adjustment.
See id.
Although both may lead to similar outcomes, there is an important structural distinction between sentencing enhancements and sentencing departures.
See United States v. Cali
Even under an advisory guidelines regime, the sentencing court is obliged to calculate the guideline range correctly.
See Gobbi
We need go no further. For the reasons elucidated above, we affirm the defendant’s conviction, vacate her sentence, and remand for resentencing consistent with this opinion.
Affirmed in part; vacated in part; and remanded for resentencing.
Notes
. Because the absence of any significantly probative evidence of inducement is disposi-tive of the claim of instructional error, we need not address the state of the record vis-a-vis predisposition.
See Capelton,
. It is conceivable, of course, that the aliens might qualify as participants for the purpose of a role-in-the-offense enhancement with respect to the "false document” count.
