David Dahlgren, a high-school senior, finds solace in running with the track team; he's a fast runner, and he enjoys the camaraderie. But team events become a source of tension when he develops a crush on one of his teammates, Sean. Scared to admit his feelings, David does everything he can to suppress them: he dates a girl, keeps his distance from his best friend who has become openly gay, and snaps a rubber band on his wrist every time he has "inappropriate" urges. Before long, Sean expresses the thoughts David has been trying to hide, and everything changes for the better. Or so it seems.
