Muggs Maloney (Leo Gorcey) is supposed to be preparing for the Golden Gloves competition but he doesn't want to train anymore in a stuffy slum building. His friend Danny (Bobby Jordan) lures him upstate to what he thinks is going to be a training camp, but instead turns out to be a Civilian Conservation Corps camp, where young men sign up to do land reclamation in exchange for support for their families -- Muggs feels cheated, but his mother can use the money and the labor is keeping him in shape, so he sticks it out, even saving the life of another boy, though his pugnacious, self-centered attitude quickly alienates most of the camp from him. When Willie (Bobby Stone), one of the few friends he has, tells Muggs that he stole $100 from the captain's office to send to his mother, Muggs decides to help him out by taking up a local fight promoter (Carleton Young) on his offer of a prize fight; he wins and tries to replace the money, but gets caught by the captain. Muggs won't squeal on Willie and is dismissed from the camp, but Danny won't let the issue go and forces Willie to confess his role in the crime.
