The East Side Kids go to the races! Mugs Maloney (Leo Gorcey) dreams of being a jockey. When an elderly thoroughbred owner agrees to train him on the condition that the gang comes up with the entry fee to a big race, Mugs agrees and the boys hit the streets for the dough. At the last minute, a substitute takes the saddle when Mugs turns out to be a terrible jockey. Disappointed, he tries to sabotage the new rider, but eventually concedes to him as the championship horse wins the race. Director Joseph H. Lewis brings the East Side Kids' endearing camaraderie home in this superior Gang romp!
