Slip and the gang (Bowery Boys) stray from newspaper work to detective work.
Sach Jones (Huntz Hall) and Slip Mahoney (Leo Gorcey) are copy boys for the New York Daily Chronicle newspaper and they hear their friend Gabe, a local police officer, has been shot in the line of duty, while trying to stop a robbery. Both boys are members of the Bowery Boys gang, and they decide to find the person who killed their friend. They soon find a lead, since another police man has been shot by the same killer, who turns out to be a mob gangster and member of the Loop Gang from Chicago. The boys then decide to go undercover to try to infiltrate the mob and expose them. They get a green light from their editor, Joe Cobb, to go and investigate the story further. They encounter two members of the Loop Gang and befriend them, with the result that they get to meet their boss, Angles Carson (Mickey Knox). Angles likes the boys and soon they are involved with the gangs next hit - a new robbery. Before long, they get to meet Angles boss, Carver (Edward Ryan), who takes a liking to them because he thinks they are tough gangsters that he can use in his operation. He lets the boys in on a plan to rob the Gotham Steel Works the next day, and Slip sends this information to the police. An ambush is set, to stop the robbery and catch the gangsters, but someone on the inside slips the information about the ambush to Carver. Carver changes his plans and instead tries to rob the Beacon Machine Works. Slip has no possibility to warn the police, but when Carver is trying to crack open the safe at Beacon Machine Works the next evening, Slip gets a chance to call his editor, who passes the information forward. Unfortunately, another employee at the Chronicle, a cartoonist named Lowell, informs Carver that the police is coming. There is a showdown between Slip and Sach and the Loop Gang members, and Slip and Sach are beat up badly. They are taken to the hospital, and once there, Sach calls for a nurse to take care of him, but when a male nurse arrives he sends him to over to Slip and gets up to leave. Just as he is about to walk out the door a female nurse comes in and takes over massaging Slips back!
