Spy Train plot
At Union Station in Los Angeles, Nazi spies Hugo and Frieda Molte and their accomplice Herman Krantz face a dilemma. Herman has placed a bag with a time bomb in the luggage locker in the cloakroom of this train station. Another identical bag containing clues that could lead to the arrest and subsequent execution of the Moltes is also found in a safe in this wardrobe. However, they dare not attempt to pick up this bag because they are being watched. Meanwhile, famed war correspondent Bruce Grant and his photographer Stew Stewart try to find the daughter of their publisher Jane Thornwald and her chambermaid Millie, who is friends with Herman, at the station.
