After gangster Phil Crowley robs a mail truck and murders its driver, postal secretary Doris Martin and postal inspector Tom Mallory are called on to track down the elusive fugitive. Disguised as a postal clerk, Doris intercepts a letter addressed to a "Jane Turner," general delivery in Los Angeles, which has been sent by Crowley's gang from their hotel hideout. Aware that it contains $10,000 in stolen cash, Tom and Doris follow the letter to Los Angeles and, with help from Banks, a local post office clerk, spot Jane Turner as she collects her mail. Doris follows Jane to her apartment, rents a neighboring apartment, then plants electronic listening devices in Jane's living room. Jane, meanwhile, offers the stolen cash not to Crowley, but to her husband Jerry's boss, from whom she believes Jerry has embezzled company funds. While helping out a penniless old man at the post office, Tom then is surprised by the appearance of another woman who identifies herself as Jane Turner. Tom alerts the postal authorities, and the second Jane Turner, whose real name is Marge Saunders, is soon apprehended with her double-crossing accomplices. By threatening to charge Eddie Parsons, Marge's boyfriend, with the robbery-murder, Tom forces Marge to reveal the gangsers' code names for both Eddie and Crowley. Tom then places a coded notice in the local newspapers' classified section, which alerts Crowley to contact Jane Turner at the apartment building where Doris has made her stake out. Through her bugging device, Doris, however, discovers that Jane picked up the money by accident and has no connection with Crowley. Concerned about the Turners' safety, Doris argues with Tom about the ethics of using them as a trap for Crowley. Before this ethical question is tested, Tom learns from his fellow investigators that, in the heat of interrogation, Eddie revealed Crowley's whereabouts to the authorities. At Crowley's hideout, Tom is involved in a shootout with one of Crowley's men, then discovers that the fugitive has already left for Jane's apartment. While Tom rushes to the scene, Doris confesses her identity to Jane and exchanges places with her in the apartment. Crowley sneaks into Jane's apartment and, assuming Doris to be Jane, demands the cash at gunpoint. Cornered, Doris uses her listening devices to alert Tom of Crowley's presence and, as Tom bursts into the apartment, shoots the surprised gangster. His mission completed, Tom proposes to Doris, who after a fight, accepts.
