The boys once again are desperate to come up with their rent money. Bud finds in the paper a chronically last-place 50-1 racehorse, Charlie Horse. He talks Mike the Cop into betting $2 with him, knowing it would never win, and Bud and Lou have lunch with it. Holding a "For Rent" sign on the sidewalk, two men, Lefty Lucas (Douglas Fowley) and his brother Joe (Paul Bryar), approach Bud and Lou and offer a job at $25 a day. They agree and learn they'll be bodyguards for them as they transport money from bank to bank. The police are alerted to be on watch for the brothers, who are vicious bank robbers. Lefty instructs a clueless Bud and Lou to stand guard at the door of the Fifth National Bank. Lefty takes the money and rushes out to take off with Joe, leaving Bud and Lou still on guard at the door who casually return to their apartment. Meanwhile, Lefty and Joe take a room in the apartment house to lay low for a while. There they listen to the race that Charlie Horse incredibly wins. Bud has Lou to return to the bank to try and borrow $200. The bank manager (Emmett Vogan) remembers Lou and simply gives him the money, thinking it is another holdup. They pay their rent and store Mike's $100 in Mr. Fields' safe. He explains to them about the bank holdups and they slowly realize they were part of both. They realize they'll need to break into Mr. Fields' safe to get the money back, but they're not the only ones after the safe.
