Returning to the city from her wealthy employer residence, Joyce Willecombe (Nancy Olson), spots two armed men on the train. She reports them to the conductor who radios in to the Station’s police. Once at Union station she points out the men to Lt. William Calhoun (William Holden), head of the station’s police squad and they find out that the gunmen are members of a gang who have kidnapped her employer’s blind daughter and are seeking a $100,000 ransom. The Chicago police headed by inspector Donnelly (Barry Fitzgerald), and the FBI are both called in. The action in this classic Film Noir culminates in a chase through the station’s underground tunnels. Directed by Rudolph Maté (D.O.A.).
