context: "Dodge" Connelly (George Clooney) is captain of the Duluth Bulldogs, a struggling professional American football team circa 1925. Dodge is determined to save both his team and pro football in general when the players lose their sponsor and the league is on the brink of collapse. He convinces Princeton University's college football star, Carter "the Bullet" Rutherford, to join the Bulldogs, hoping to capitalize on Carter's fame as a decorated hero of the First World War (like Alvin York, he single-handedly captured a large group of German soldiers). In addition to his legendary tales of combat heroism, Carter has dashing good looks and unparalleled speed and skill on the field. As a result of his presence, both the Bulldogs and pro football in general begin to prosper.
  Chicago Tribune newspaper reporter Lexie Littleton becomes the object of the affections of both Dodge and Carter. Lexie has been assigned to find proof that Carter's war heroics are bogus. Carter confesses that the surrender of the Germans was a lucky accident and that his role in it was more foolish than heroic. Carter soon discovers Lexie's agenda and is doubly hurt when he learns that Dodge and Lexie are starting to show affections for each other and even shared a kiss. The ensuing fight over Lexie's affections puts her off. Spurred on by the threats of Carter's manager, she decides to publish the story.
  The story sparks a firestorm of accusations and reprimands. Carter's manager resorts to shady dealing to cover it up, even bribing the original witness to change his story.
  Dodge's attempts to legitimize pro football take a life of its own. The new commissioner formalizes the game's rules, taking away improvisational antics. In addition, the commissioner takes the responsibility of clearing up the Carter controversy to set an example for the new direction of professional football.
  With the whole world against Lexie (even the Tribune is pushing her to retract her story), Dodge concocts a clever ruse. Interrupting a private hearing in the commissioner's office, Dodge threatens Carter with a confrontation by his old army mates. Dodge claims that they are just outside the door, ready to congratulate him for his heroic actions. In truth, the men are Bulldogs in borrowed Army uniforms.
  Carter confesses the truth. The commissioner frees Lexie from printing a retraction. Carter is ordered to simply say he got too much credit for his war actions, but must give a hefty part of his paycheck to the American Legion. Carter's conniving manager is banned from football as well. Dodge is warned that if he pulls any old tricks to win the next game, he will lose his place in the league.
  Dodge plays in one last game. This time it will be against Carter, who has changed sides from Duluth to Chicago. The rivalry for Lexie's affection spills onto the field.
  The game does not go well for Dodge, including how muddy the field is. Dodge decides football should be played without rules. Lexie notices that after a brawl, Dodge is missing and with most players covered in mud, no one can tell who is who. There appears to be an interception and Chicago seems to have won, but when the mud is removed it is seen that the player is none other than Dodge Connelly, who disguised himself as a Chicago player on the play. The play is changed from an interception to a touchdown, and the Bulldogs win.
  Carter mentions to Dodge that he is finished playing football, based on the threat the commissioner had made. He intends to tell the newspapers the real story about his "capture" of the German soldiers. Dodge argues that America "needs" heroes and it is implied the true story will not be told. Dodge and Carter part on good terms once again.
  After the game, Dodge meets up with Lexie and they ride into the sunset on Dodge's motorbike, discussing with humor the possibilities in their future, which include bankruptcy, scandals and jail time. During the end credits, pictures show Dodge and Lexie getting married, Carter donating $10,000 to the US military and Carter's former manager with new clients Babe Ruth and Lou Gehrig.
