Coach McGann is nearly voted out of a job because his varsity football team has been on a losing streak, but is given one more season to improve the team. With the pressure on, Coach begins training his men with the help of Doc Saunders, and divides the squad into three teams. Bob Potter makes the second team, but Larry Royal feels humiliated because he is assigned to the third team. In the midst of training, the players work hard to keep their grades up, but three of Coach's best varsity men are kicked out because of their poor academic scores. Coach selects Bob and Larry to replace the lost players, which fills Bob's girl friend, Marian Stuart, with pride, and also swells Larry's head a little more. After a game in which Bob helps the team to win, Coach assigns him to run interference for Larry, who is now the quarterback. Larry becomes insufferably egotistical after the team wins game after game because of his touchdowns, but Bob remains humble. When Marian publishes an article in the school paper saying that Larry could never have made the touchdowns without Bob's help, Bob becomes angry at her because he is afraid the article will cause conflict between him and Larry. Resentful of Bob's anger, Marian agrees to go out to the swing café with Larry. Bob's friend, Jay Hill, becomes drunk and, sick of Larry's pomposity, picks a fight with him, but Larry thinks Bob sent him over to humiliate him, so he fights with Bob. During the scuffle, a table falls on Bob's leg, and he is sent to the doctor. Although nothing is wrong with his leg, Bob pretends he is injured so he can stay on the bench and prove to Larry that he cannot make touchdowns without his help. The plan works, as Larry is unable to make touchdowns without Bob running interference. Unable to endure the thought of his team losing and Coach's job being jeapordized, Bob confesses his duplicity to Coach, who does not believe him. Bob puts himself in the game, apologizes to Larry, who does likewise, and together, they win the game. Coach suspends Bob for the rest of the season for lying, but promises to take him on next year, after which Marian and Bob are reunited.
