Mountain Rivera is at the end of his boxing career after a knockout by Cassius Clay in the seventh round. His left eye is one punch from permanent trauma, his ears turned to cauliflower, his speech slurred from “being hit a million times,” and he slings punches anytime he hears a bell, but his trainer and ‘cutman’ Army, and Miss Miller, a manipulative social worker, support his illusion that he could be a movie usher, a camp counselor, or a romantic partner for Miller.
