  Justice Kennedy
  delivered the opinion of the Court.
  We consider here the circumstances under which a defendant who has entered a plea of guilty to a criminal charge may assert a double jeopardy claim in a collateral attack upon the sentence. Respondents, upon entering guilty pleas, were convicted of two separate counts of conspiracy, but contend now that only one conspiracy existed and that double jeopardy principles require the conviction and sentence on the second count to be set aside. The United States Court of Appeals for the Tenth Circuit held that respondents were entitled to introduce evidence outside the original record supporting their claim and directed further proceedings in the District Court. We hold that the double jeopardy challenge is foreclosed by the guilty pleas and the judgments of conviction.

  A
  Respondents, Ray C. Broce and Broce Construction Co., Inc., bid for work on highway projects in Kansas. Two of the contracts awarded to them became the subject of separate indictments charging concerted acts to rig bids and suppress competition in violation of the Sherman Act, 26 Stat. 209, as amended, 15 U. S. C. § 1. The relevant portions of the indictments are set forth in the Appendix to our opinion. The first indictment charged respondents with entering into an agreement, sometime in or about April 1978, to rig bids on a particular highway project. The second charged respondents with entering into a similar agreement, sometime in or about July 1979, to rig bids on a different project. Both indictments were discussed during plea negotiations, and respondents acknowledged in plea agreements that they were subject to separate sentences on each conspiracy charged. Plea Agreement between the United States of America and Defendant Ray C. Broce, App. to Pet. for Cert. 126a, 127a; Plea Agreement between the United States of America and Defendant Broce Construction Co., Inc., App. to Pet. for Cert. 133a, 134a.
  Respondents pleaded guilty to the two indictments in a single proceeding. The District Court conducted a hearing fully in accord with Rule 11 of the Federal Rules of Criminal Procedure and found that the pleas were free and voluntary, made with an understanding of their consequences and of the nature of the charges. Respondents had counsel at all stages and there are no allegations that counsel was ineffective. Convictions were entered on the pleas. The District Court then sentenced Broce to two years’ imprisonment on each count, the terms to run concurrently, and to a fine of $50,000 on each count. Broce was also sentenced for mail fraud under 18 U. S. C. § 1341, a conviction which is not relevant here. The corporation was fined $750,000 on each count, for a total of $1,500,000. Neither respondent having appealed, the judgments became final.
  B
  On the same day that respondents entered their pleas, an indictment was filed against Robert T. Beachner and Beachner Construction Co. charging a violation of both the Sherman Act and the mail fraud statute. The indictment alleged a bid-rigging conspiracy involving yet a third Kansas highway construction project. These defendants, however, chose a different path than that taken by the Broce respondents: they proceeded to trial and were acquitted. After the acquittal in the Beachner case (Beachner I), a second indictment was returned by the grand jury charging Beachner Construction Co. with three new Sherman Act violations and three new acts of mail fraud. The Sherman Act counts charged bid-rigging conspiracies on three Kansas highway projects not mentioned in Beachner I.
  Once again, Beachner pursued a different strategy than that followed by Broce and Broce Construction Co. Prior to trial, Beachner moved to dismiss the indictment on the ground that the bid-rigging arrangements identified were merely smaller parts of one overarching conspiracy existing among Kansas highway contractors to rig highway bids within the State. In light of its acquittal in Beachner I, the company argued that a second prosecution would place it in double jeopardy.
  The District Court granted the motion to dismiss. United States v. Beachner Construction Co., 555 F. Supp. 1273 (Kan. 1983) (Beachner II). It found that a “continuous, cooperative effort among Kansas highway contractors to rig bids, thereby eliminating price competition, has permeated the Kansas highway construction industry in excess of twenty-five years, including the period of April 25, 1978, to February 7, 1980, the time period encompassed by the Beachner I and Beachner II indictments.” Id., at 1277. The District Court based the finding on its determination that there had been a common objective among participants to eliminate price competition, a common method of organizing bidding for projects, and a common jargon throughout the industry, and that mutual and interdependent obligations were created among highway contractors. Concluding that the District Court’s findings were not clearly erroneous, the Court of Appeals affirmed the dismissal. United States v. Beachner Construction Co., 729 F. 2d 1278 (CA10 1984).
  C
  One might surmise that the Broce defendants watched the Beachner proceedings with awe, if not envy. What is certain is that the Broce defendants sought to profit from Beachner’s success. After the District Court issued its decision to dismiss in Beachner II, the Broce respondents filed a motion pursuant to Federal Rule of Criminal Procedure 35(a) to vacate their own sentences on the Sherman Act charge contained in the second indictment. Relying on Beachner II, they argued that the bid-rigging schemes alleged in their indictments were but a single conspiracy. The District Court denied the motion, concluding that respondents’ earlier guilty pleas were an admission of the Government’s allegations of two conspiracies, an admission that foreclosed and concluded new arguments to the contrary. Nos. 81-20119-01 and 82-20011-01 (Kan., Nov. 18, 1983), App. to Pet. for Cert. 112a.
  A panel of the Court of Appeals for the Tenth Circuit reversed. 753 F. 2d 811 (1985). That judgment was vacated and the case reheard en banc. Citing our decisions in Blackledge v. Perry, 417 U. S. 21 (1974), and Menna v. New York, 423 U. S. 61 (1975) (per curiam), a divided en banc court concluded that respondents were entitled to draw upon factual evidence outside the original record, including the Beachner II findings, to support the claim of a single conspiracy. 781 F. 2d 792 (1986). The en banc court rejected the Government’s argument that respondents had waived the right to raise their double jeopardy claim by pleading guilty, holding that the Double Jeopardy Clause “does not constitute an individual right which is subject to waiver.” Id., at 795. It further rejected the Government’s contention that respondents’ guilty pleas must be construed as admissions that there had been separate conspiracies. The Court of Appeals observed that the indictments did not “specifically allege separate conspiracies,” and held that “the admissions of factual guilt subsumed in the pleas of guilty go only to the acts constituting the conspiracy and not to whether one or more conspiracies existed.” Id., at 796.
  On remand, the District Court, citing Beachner II, concluded that the indictments merely charged different aspects of the same conspiracy to restrain competition. It vacated the judgments and sentences entered against both respondents on the second indictment. Nos. 81-20119-01 and 82-20011-01 (Kan., June 30, 1986), App. to Pet. for Cert. 5a. In its decision on appeal from that judgment, the Court of Appeals noted that our intervening decision in Ricketts v. Adamson, 483 U. S. 1 (1987), made clear that the protection against double jeopardy is subject to waiver. Nonetheless, it concluded that while Ricketts invalidated the broader rationale underlying its earlier en banc opinion that double jeopardy protections could not be waived, it left intact its narrower holding that the guilty pleas in this case did not themselves constitute such waivers. It then held that the District Court’s finding of a single conspiracy was not clearly erroneous, and affirmed. Nos. 86-2166 and 86-2202 (CA10, Aug. 18, 1987), App. to Pet. for Cert. la. We granted certiorari, 485 U. S. 903 (1988).
  II
  A plea of guilty and the ensuing conviction comprehend all of the factual and legal elements necessary to sustain a binding, final judgment of guilt and a lawful sentence. Accordingly, when the judgment of conviction upon a guilty plea has become final and the offender seeks to reopen the proceeding, the inquiry is ordinarily confined to whether the underlying plea was both counseled and voluntary. If the answer is in the affirmative then the conviction and the plea, as a general rule, foreclose the collateral attack. There are exceptions where on the face of the record the court had no power to enter the conviction or impose the sentence. We discuss those exceptions below and find them inapplicable. The general rule applies here to bar the double jeopardy claim.
  A
  The Government’s petition for certiorari did not seek review of the determination that the bid-rigging described in the two Broce indictments was part of one overall conspiracy. Instead, the Government challenges the theory underlying the en banc judgment in the Court of Appeals that respondents were entitled, notwithstanding their earlier guilty pleas, to a factual determination on their one-conspiracy claim. That holding was predicated on the court’s view that, in pleading guilty, respondents admitted only the acts described in the indictments, not their legal consequences. As the indictments did not include an express statement that the two conspiracies were separate, the Court of Appeals reasoned, no such concession may be inferred from the pleas.
  In holding that the admissions inherent in a guilty plea “go only to the acts constituting the conspiracy,” 781 F. 2d, at 796, the Court of Appeals misapprehended the nature and effect of the plea. A guilty plea “is more than a confession which admits that the accused did various acts.” Boykin v. Alabama, 395 U. S. 238, 242 (1969). It is an “admission that he committed the crime charged against him.” North Carolina v. Alford, 400 U. S. 25, 32 (1970). By entering a plea of guilty, the accused is not simply stating that he did the discrete acts described in the indictment; he is admitting guilt of a substantive crime. That is why the defendant must be instructed in open court on “the nature of the charge to which the plea is offered,” Fed. Rule Crim. Proc. 11(c)(1), and why the plea “cannot be truly voluntary unless the defendant possesses an understanding of the law in relation to the facts,” McCarthy v. United States, 394 U. S. 459, 466 (1969).
  Just as a defendant who pleads guilty to a single count admits guilt to the specified offense, so too does a defendant who pleads guilty to two counts with facial allegations of distinct offenses concede that he has committed two separate crimes. The Broce indictments alleged two distinct agreements: the first, an agreement beginning in April 1978 to rig bids on one specified highway project, and the second, an agreement beginning 15 months later to rig bids on a different project. The Court of Appeals erred in concluding that because the indictments did not explicitly state that the conspiracies were separate, respondents did not concede their separate nature by pleading guilty to both. In a conspiracy charge, the term “agreement” is all but synonymous with the conspiracy itself, and as such has great operative force. We held in Braverman v. United States, 317 U. S. 49, 53 (1942), that “[t]he gist of the crime of conspiracy as defined by the statute is the agreement... to commit one or more unlawful acts,” from which it follows that “the precise nature and extent of the conspiracy must be determined by reference to the agreement which embraces and defines its objects.” A single agreement to commit several crimes constitutes one conspiracy. By the same reasoning, multiple agreements to commit separate crimes constitute multiple conspiracies. When respondents pleaded guilty to two charges of conspiracy on the explicit premise of two agreements which started at different times and embraced separate objectives, they conceded guilt to two separate offenses.
  Respondents had the opportunity, instead of entering their guilty pleas, to challenge the theory of the indictments and to attempt to show the existence of only one conspiracy in a trial-type proceeding. They chose not to, and hence relinquished that entitlement. In light of Beachner, respondents may believe that they made a strategic miscalculation. Our precedents demonstrate, however, that such grounds do not justify setting aside an otherwise valid guilty plea.
  In Brady v. United States, 397 U. S. 742 (1970), the petitioner had been charged with kidnaping in violation of what was then 18 U. S. C. § 1201(a) (1964 ed.). He entered a knowing and voluntary plea of guilty. Nine years after the plea, we had held in United States v. Jackson, 390 U. S. 570 (1968), that the provision of § 1201(a) providing for a death penalty only upon the recommendation of the jury was unconstitutional. This was of no avail to Brady, however, because the possibility that his plea might have been influenced by an erroneous assessment of the sentencing consequences if he had proceeded to trial did not render his plea invalid. We observed:
  “A defendant is not entitled to withdraw his plea merely because he discovers long after the plea has been accepted that his calculus misapprehended the quality of the State’s case or the likely penalties attached to alternative courses of action. More particularly, absent misrepresentation or other impermissible conduct by state agents, a voluntary plea of guilty intelligently made in the light of the then applicable law does not become vulnerable because later judicial decisions indicate that the plea rested on a faulty premise.” 397 U. S., at 757 (citation omitted).
  Similarly, we held in McMann v. Richardson, 397 U. S. 759 (1970), that a counseled defendant may not make a collateral attack on a guilty plea on the allegation that he misjudged the admissibility of his confession. “Waiving trial entails the inherent risk that the good-faith evaluations of a reasonably competent attorney will turn out to be mistaken either as to the facts or as to what a court’s judgment might be on given facts.” Id., at 770. See also Tollett v. Henderson, 411 U. S. 258, 267 (1973) (“[J]ust as it is not sufficient for the criminal defendant seeking to set aside such a plea to show that his counsel in retrospect may not have correctly appraised the constitutional significance of certain historical facts, it is likewise not sufficient that he show that if counsel had pursued a certain factual inquiry such a pursuit would have uncovered a possible constitutional infirmity in the proceedings”) (citation omitted).
  Respondents have submitted the affidavit of Kenneth F. Crockett, who served as their attorney when their pleas were entered. App. 72-73. Crockett avers that he did not discuss double jeopardy issues with respondents prior to their pleas, and that respondents had not considered the possibility of raising a double jeopardy defense before pleading. Respondents contend that, under these circumstances, they cannot be held to have waived the right to raise a double jeopardy defense because there was no “intentional relinquishment or abandonment of a known right or privilege.” Johnson v. Zerbst, 304 U. S. 458, 464 (1938).
  Our decisions have not suggested that conscious waiver is necessary with respect to each potential defense relinquished by a plea of guilty. Waiver in that sense is not required. For example, the respondent in Tollett pleaded guilty to first-degree murder, and later filed a petition for habeas corpus contending that his plea should be set aside because black citizens had been excluded from the grand jury that indicted him. The collateral challenge was foreclosed by the earlier guilty plea. Although at the time of the indictment the facts relating to the selection of the grand jury were not known to respondent and his attorney, we held that to be irrelevant:
  “If the issue were to be cast solely in terms of ‘waiver,’ the Court of Appeals was undoubtedly correct in concluding that there had been no such waiver here. But just as the guilty pleas in the Brady trilogy were found to foreclose direct inquiry into the merits of claimed antecedent constitutional violations there, we conclude that respondent’s guilty plea here alike forecloses independent inquiry into the claim of discrimination in the selection of the grand jury.” 411 U. S., at 266.
  See also Menna, 423 U. S., at 62, n. 2 (“[W]aiver was not the basic ingredient of this line of cases”).
  The Crockett affidavit, as a consequence, has no bearing on whether respondents’ guilty plea served as a relinquishment of their opportunity to receive a factual hearing on a double jeopardy claim. Relinquishment derives not from any inquiry into a defendant’s subjective understanding of the range of potential defenses, but from the admissions necessarily made upon entry of a voluntary plea of guilty. The trial court complied with Rule 11 in ensuring that respondents were advised that, in pleading guilty, they were admitting guilt and waiving their right to a trial of any kind. A failure by counsel to provide advice may form the basis of a claim of ineffective assistance of counsel, but absent such a claim it cannot serve as the predicate for setting aside a valid plea.
  In sum, as we explained in Mabry v. Johnson, 467 U. S. 504, 508 (1984), “[i]t is well settled that a voluntary and intelligent plea of guilty made by an accused person, who has been advised by competent counsel, may not be collaterally attacked.” That principle controls here. Respondents have not called into question the voluntary and intelligent character of their pleas, and therefore are not entitled to the collateral relief they seek.
  B
  An exception to the rule barring collateral attack on a guilty plea was established by our decisions in Blackledge v. Perry, 417 U. S. 21 (1974), and Menna v. New York, supra, but it has no application to the case at bar.
  The respondent in Blackledge had been charged in North Carolina with the state-law misdemeanor of assault with a deadly weapon. Pursuant to state procedures, he was tried in the county District Court without a jury, but was permitted, once he was convicted, to appeal to the county Superior Court and obtain a trial de novo. After the defendant filed an appeal, the prosecutor obtained an indictment charging felony assault with a deadly weapon with intent to kill and inflict serious bodily injury. The defendant pleaded guilty. We held that the potential for prosecutorial vindictiveness against those who seek to exercise their right to appeal raised sufficiently serious due process concerns to require a rule forbidding the State to bring more serious charges against defendants in that position. The plea of guilty did not foreclose a subsequent challenge because in Blackledge, unlike in Brady and Tollett, the defendant’s right was “the right not to be haled into court at all upon the felony charge. The very initiation of proceedings against him . . . thus operated to deny him due process of law.” 417 U. S., at 30-31.
  The petitioner in Menna had refused, after a grant of immunity, to obey a court order to testify before a grand jury. He was adjudicated in contempt of court and sentenced to a term in civil jail. After he was released, he was indicted for the same refusal to answer the questions. He pleaded guilty and was sentenced, but then appealed on double jeopardy grounds. The New York Court of Appeals concluded that Menna had waived his double jeopardy claim by pleading guilty. We reversed, citing Blackledge for the proposition that “[w]here the State is precluded by the United States Constitution from haling a defendant into court on a charge, federal law requires that a conviction on that charge be set aside even if the conviction was entered pursuant to a counseled plea of guilty.” 423 U. S,, at 62. We added, however, an important qualification:
  “We do not hold that a double jeopardy claim may never be waived. We simply hold that a plea of guilty to a charge does not waive a claim that —judged on its face — the charge is one which the State may not constitutionally prosecute.” Id., at 63, n. 2 (emphasis added).
  In neither Blackledge nor Menna did the defendants seek further proceedings at which to expand the record with new evidence. In those cases, the determination that the second indictment could not go forward should have been made by the presiding judge at the time the plea was entered on the basis of the existing record. Both Blackledge and Menna could be (and ultimately were) resolved without any need to venture beyond that record. In Blackledge, the concessions implicit in the defendant’s guilty plea were simply irrelevant, because the constitutional infirmity in the proceedings lay in the State’s power to bring any indictment at all. In Menna, the indictment was facially duplicative of the earlier offense of which the defendant had been.convicted and sentenced so that the admissions made by Menna’s guilty plea could not conceivably be construed to extend beyond a redundant confession to the earlier offense.
  “[Filed: Nov. 17, 1981]
  Respondents here, in contrast, pleaded guilty to indictments that on their face described separate conspiracies. They cannot prove their claim by relying on those indictments and the existing record. Indeed, as noted earlier, they cannot prove their claim without contradicting those indictments, and that opportunity is foreclosed by the admissions inherent in their guilty pleas. We therefore need not consider the degree to which the decision by an accused to enter into a plea bargain which incorporates concessions by the Government, such as the one agreed to here, heightens the already substantial interest the Government has in the finality of the plea. The judgment of the Court of Appeals is
  Reversed.

  “(e) Discussing the payment of consideration of value to another contractor to induce that contractor to submit a noncompetitive, rigged bid on the above-referenced public highway construction project.”
  That is certainly how all participants viewed the indictments at the time. As noted earlier, see siupra, at 565, respondents acknowledged in their plea agreements that they were subject to receiving separate sentences for each offense to which they were pleading. Furthermore, the District Judge informed Broce at the Rule 11 hearing of the maximum punishment “on each charge,” and Broce stated that he understood. App. 36. Prior to sentencing, the Government prepared an “Official Version of the Offense” for inclusion in the presentence report which stated that there were “two separate conspiracies” giving rise to the indictments. Id., at 51. At his sentencing hearing, Broce was given an opportunity to state “any dispute with what the government has included in the pre-sentence report about the official version of the offense,” and did not dispute the statement that the conspiracies were separate ones. Id., at 63-64. We do not suggest that any of these events are necessary to our holding that respondents have forfeited the opportunity to dispute the separate nature of the conspiracies; on the contrary, the guilty pleas are alone a sufficient basis for that conclusion. We review' these incidents simply to note that our reading of the indictments is the necessary one, and was shared by all participants to the plea proceedings at the time the pleas were entered.
