The East Side Kids find themselves in another jam when Muggs (Leo Gorcey) takes up boxing. The rest of the gang aren't pleased with his unsportsmanlike behavior, but when he takes the rap for a theft he didn't commit, the old street camaraderie kicks into action. Directed by B movie master Joseph H. Lewis (Gun Crazy), this rowdy feature from Monogram Pictures also stars Bobby Jordan, Donald Haines, and Sunshine Sammy Morrison, plus Leo Gorey's younger brother David as "Peewee!"
