Sharon Carmody asks her friend, ex-boxer Duke Maronek, to walk her home as a man, Art Grover, has been harassing her. When they arrive at her apartment, they hear movement inside and Duke goes in alone, only to be jumped by someone inside. Sharon calls the police from a pay phone in the hall. After the melee, Duke finds his attacker dead behind the sofa. Sharon, a model who is up for a major sponsorship job as the White Snow Princess, begs him to dispose of the body so as not to hurt her chances before the police arrive. He does so but consults Perry Mason, who has helped Duke before, late that night. He rejects Perry's advice that he go to the police because of Sharon and because he is afraid of confinement in small places. But when another man is charged with killing the man, Perry is forced to act. He tries to convince Sharon to come forward but she won't and is a near lock to win the job of her dreams. Duke is soon on the run and Perry begins to think that someone else might be responsible for the murder.
