Sailors Laurel and Hardy disembark and book in a sleazy hotel. The owner Mugsie Long intends to marry a young girl against her wishes, but Stan and Ollie come to her rescue. After fleeing the hotel, the boys find out they've left their money in their room, but an old pal of Ollie's offers $50 if Ollie will fight in a boxing ring that night. Ollie agrees but predictably makes Stan the fighter and himself the manager. The catch is Stan's opponent is Mugsie himself. Knowing how tough Mugsie is (both he and Stan had earlier thrown billiard balls at his head to knock him out, only to see them bounce off his head with no effect to him whatsoever), Ollie makes a seemingly wise bet with a drunk on Mugsie to win. The drunk accepts the bet, making himself seem to Ollie a sucker. Seeing Stan as his opponent, Mugsie loads his glove with metal before the fight begins. However, during the course of the fight, Mugsie and Stan accidentally switch gloves, causing Mugsie to comically run away from Stan knowing he has the loaded glove. Stan, who doesn't realize the glove is loaded despite it weighing his arm down, manages to knock out Mugsie when the latter tries to pull the loaded glove off Stan's hand and winds up knocking himself out. Ollie winces in defeat while the drunk chuckles in triumph; turns out he wasn't so much a sucker after all! Mugsie's second calls a policeman and tells him Stan had been fighting with a loaded glove. Ollie is forced to give the drunk the money they received for entering the fight, to Stan's consternation, until Ollie explains, "I bet on you to lose and you double-crossed me!" Stan, enraged at his own buddy and manager betting against him, starts to knock Ollie out cold...but as he draws his fist back, he accidentally knocks out the policeman investigating about the loaded glove, ironically still on his hand! Stan and Ollie flee the stadium in terror.
