After winning the lightweight championship, Billy Brooks is rushed into the bright lights of Broadway;s Great White Way, along with his flighty wife, Phyllis. Ace O’Brien, the manager of Billy’s next opponent, tries to weaken Brooks by getting him into all kinds of parties and also by trying to break up his love for Phyllis. He employs delightful Deloari, Broadway vamp-for-hire, to aid him and Delorai does her work so well that Brooks loses the fight. He, his manager and his trainer go to the Brooks apartment where Phyllis is throwing a big party, and the angry Brooks poops on the party and throws all attendees out. Phyllis leaves him. On the night of his comeback fight, Phyllis is injured in an automobile accident and taken to a hospital where her condition is diagnosed as serious. Brooks is kept from knowing about it until just before his fight. When he is told that Phyllis is listening to the fight on the radio, Brooks quickly dispatches his opponent and heads for a reconciliation with Phyllis.
