A man is mistaken for a champion fighter.

At a training camp preparing for a heavyweight championship bout are Georges La Verne with Pop O'Keefe, his manager; Nosey Bartlett, the camp cook; and Gink Schiner, a lazy, second-rate fighter who is to appear in a preliminary before the big fight. Although Georges is pursued by society girl Norine Lloyd, he is more interested in Sue Burke, his advisor and childhood playmate; Toots, Gink's sweetheart, is constantly concerned over Gink's flirting with pretty girls. Larkin, manager of champion Bob Morgan, comes to the camp and attempts to have the fight "fixed," but O'Keefe informs him Georges will do his best. The Kicker is delegated by Larkin to incapacitate Georges at a party with a knockout pill, but Gink switches his drink with Nosey's. To everyone's surprise, Gink wins his bout. Before his fight, Georges is accosted by Morgan, and he fares badly in the ring until, with a change of tactics, he knocks out Morgan and wins the title.
