George Nader plays a reporter whose career is ruined by liquor. A comeback opportunity presents itself when Nader is a bystander at the arrest of a well-known criminal. The reporter knows that the crook, who has been accused of an ambush murder, is innocent, and he sets about to collar the real killer. Nader goes "cold turkey" on the booze despite tempations at every turn, and gets his man. Appointment with a Shadow is one of a handful of films directed by onetime I Led 3 Lives star Richard Carlson.
