Union Station

Returning to the city from the home of her wealthy employer, Henry Murchison, (Herbert Heyes), Joyce Willecombe (Nancy Olson), spots two armed men on the train. She reports them to the conductor with the result that the train is met at Union Station by Lt. William Calhoun (William Holden), head of the station's police squad. Joyce points out the men to Calhoun and it is later learned that they're members of a gang that has kidnapped Murchison's blind daughter, Lorna (Allene Roberts). The city police headed by Inspector Donnelly (Barry Fitzgerald), and the FBI are called in. The kidnappers use Union Station as the central point for contacting Murchison/ Calhoun's men are everywhere, vigilant but not interfering, lest the criminal kill the girl after collecting the $100,000 ransom.
