Amateur sleuth Tom Lawrence (
Tom Conway) known as "The Falcon," is approached by Mia Bruger (
Rita Corday) to help in finding her brother, who had gone missing. When Tom goes to a cocktail bar, he is attacked and knocked unconscious. When he revives, he finds himself in his car on a country road. A motorcycle police officer stops him and arrests him, because Police Inspector Timothy Donovan (Cliff Clark) has put out an "all-points" bulletin for his arrest in the case of a murdered bank official and the theft of $250,000 in
war bonds. Although the Falcon has an alibi with his fiancée, reporter Marcia Brooks (
Jane Randolph) and assistant, "Goldie" Locke (
Cliff Edwards) supporting him, Donovan is skeptical and attempts to incarcerate Tom, who makes his escape. Returning to the bar, it is now the headquarters of a woman's knitting society, run by Geraldine Lipton (
Wynne Gibson). When the trio of sleuths head off to Lipton's resort hotel, they find a number of suspicious individuals, hotel manager Gwynne Gregory (
Harriet Hilliard), former criminal Rickey Davis (Erford Gage), a nurse to invalid Bruno Steffen (
André Charlot) and Mia. When Tom approaches Mia, she pretends that she doesn't know him and dives into the pool but as she hits the water, she is killed by a gunshot. Looking for the killer, Tom runs into puppeteer Smiley Dugan (
Edgar Kennedy), who alerts Donovan that the Falcon is at the hotel. Picking up a cigarette case that might be a clue to the murderer, Tom has to work quickly before Donovan arrives. Marcia reports that the fingerprints on the cigarette case belong to a notorious thief known as "the Duchess". Tom phones his houseboy, Jerry (
Richard Loo), telling him to pose as the Chinese Trade Commissioner wanting to buy war bonds. After Steffen confides to Jerry that he plans to buy war bonds from Gwynne, Tom exposes Mrs. Lipton as the Duchess, and accuses her of stealing the bonds, but Donovan, with a warrant for murder, arrests Tom, Marcia, Goldie and Jerry instead. Finding a way to escape once again, Tom returns to the hotel, and confronts Mrs. Lipton, who was being blackmailed by Rickey into selling the war bonds. When Rickey is killed, a terrified Gwynne confesses that she was involved because Rickey was her husband. When he is trapped in an elevator with Gwynne, Tom realizes that the killer is still in the hotel. Finding a way out, Tom rushes to Mrs. Lipton's room to find the puppeteer threatening the hotel owner. When Tom tries to apprehend him, Dugan falls to his death. Donovan, now convinced in Tom's innocence, arrives to arrest Mrs. Lipton for the theft of the war bonds. ==Cast==
