Sach Jones and Slip Mahoney are copy boys for the New York Daily Chronicle newspaper who hear that two local police officers, including their friend Gabe, have been shot in the line of duty while trying to stop a robbery.
Gabe survives, but his partner does not, so they decide to help find the person responsible - a gangster and member of the Loop Gang from Chicago.
Before long, they get to meet Angles' boss, Carver, 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.
Warner Archives released the film on made-to-order DVD in the United States as part of "The Bowery Boys, Volume Three" on October 1, 2013.
