Kimble works as a driver and stockroom clerk at Denshaw's department store. He overhears Pascoe needling Martin Rowland (actor Leslie Neilsen) about Rowland marrying the daughter of the founder of the store, Ginny Rowland (actress Diana Van der Vlis), to achieve his position at the top. When Pascoe, out in the parking lot, suggests that he has been fooling around with Ginny, Martin hits Pascoe in the face. Unfortunately, Martin is a former sports hero, and Pascoe dies from this single punch. Unknown to Martin, Kimble is a witness.
Vagabond Arthur Tibbets comes along, finds Pascoe on the ground, and steals his wallet and watch. Tibbets is arrested for murder. Kimble anonymously contacts the Rowlands to get Martin to tell the truth and clear the innocent man. Ginny, seeking to avoid embarrassment, employs Angstrom (actor Edward Binns), a former policeman and now store security chief, to get to the bottom of it and eliminate the threat to Martin and herself. Kimble should leave town, but he cannot allow an innocent man to be convicted of murder.
