At Chicago Union Station (though filmed at Los Angeles Union Station[3]), Police Lieutenant William "Bill" Calhoun is approached by an apprehensive passenger named Joyce Willecombe who believes that two men aboard her train may be up to no good. The two men deposit a suitcase in a storage locker. When Bill retrieves it, Joyce recognizes the clothing as belonging to Lorna Murchison, the blind daughter of wealthy Henry Murchison, Joyce's employer. When Mr. Murchison is brought in, he admits Lorna has been kidnapped and held for ransom, but does not want the police to get involved as they might endanger his daughter's life. Bill and his boss, Inspector Donnelly, persuade him to accept their help. The railway station where Calhoun works has been chosen as the location to pay off the ransom. Bill and Donnelly race against time to save Lorna and bring the kidnappers to justice. When the kidnappers make contact with Murchison at the station, Joyce recognizes them. The police trail one of them, Gus Hadder, but he spots them and runs, only to die in an accident. The police prevent his death from being reported in the newspapers. Later, Joyce spots Joe Beacom, the leader of the gang, and sees a third kidnapper, Vince Marley. Beacom drives away (though Joyce memorizes the license plate number), but the police arrest Marley. When he refuses to talk, Donnelly tells Bill to kill him and make his death look accidental. When the policemen pretend to prepare to throw Marley in front of an arriving train, he breaks and tells them where Lorna is being held. However, Beacom and his girlfriend Marge Wrighter have already taken Lorna somewhere else by the time they break in....
