Plot
Charlie Drake plays honest but naive locksmith Ernest Wright who believes that everybody else is equally honest. First, he is duped by a debonair con man into opening a car. He is caught by the police but given probation. Next, the same man fools him into breaking into a house, and again he is caught while the villain escapes and he lands in jail. When he is released, he again gets tricked, this time by a woman, into opening a safe, for which he receives a three-year jail sentence. On arrival in prison, he has a reputation as a master thief. Upon his release, he finds himself as a pawn being manipulated by two gangs into a safe-cracking scheme but, with the help of undercover policewoman Muriel, he helps trap the crooks and clear his name. Portions of the film satirise the 1962 films '' Birdman of Alcatraz'' and '' Dr. No'', Drake's hit song '' My Boomerang Won't Come Back'', and the Ceremony of the Keys at theCast
