This eighth entry in the East Side Kids series finds the boys shipped off to reform school, where their leader Muggs McGinnis (Leo Gorcey) earns the nickname "Mr. Wise Guy", while Danny, Glimpy, and the rest of the gang run up against troublemakers with nicknames like "Chalky" and "Rice Pudding". But when they discover the thug responsible for landing them there in the first place is the same one who framed their friend for murder, the wily kids bust out with a plan to bring him to justice. Billy Gilbert co-stars as the nasty bad guy.
