Muggs McGinnis, bully and champion boxer of New York City's Eastside, is scheduled to box the Westside champion. In a pool game just before the match, he pulls a fast one on Harry Wycoff, local thug, so the latter decides to have Muggs abducted and place a winning bet on his opponent against whomever replaces Muggs. Danny Lyons, runner-up in last year's Eastside tournament, takes Muggs' place and wins the match. Believing Danny is the one who had him abducted, Muggs tries to pick a fight with him. Danny, who is in love with Muggs' sister, Ivy, refuses to fight in the street. When Danny and Ivy later win a jitterbug competition where Muggs is disqualified, Muggs' resentment against Danny balloons. When Danny joins the U.S. Army, Muggs sets out to frame Danny on a theft charge, forcing Danny to make a stand.—Les Adams <[email protected]>
