The Kid from Brooklyn

Burleigh Sullivan, a well-meaning milkman, encounters Polly Pringle during his early-morning rounds. He recognizes her talent and tries to help by getting her a job at the club where his sister Susie performs. His efforts backfire and he ends up getting sacked from his route.

After Susie finishes her show, Burleigh witnesses his sister Susie being molested by the drunken boxer Speed McFarlane and his bodyguard Spider. He intervenes, sparking a fracas in which Speed is knocked out and Gabby Sloan erupts in anger. The incident draws media attention and sets Gabby on the path to turning Burleigh into a fighter.

Newspapers and photographers replay the incident, showing Burleigh knocking out Speed. In truth, Spider was responsible for Speed's KO due to Burleigh's quick footwork, but the public misreads who is to blame. Gabby Sloan decides to capitalize on the publicity by turning Burleigh into a boxing star.

Burleigh embarks on a boxing tour, but his opponents are paid to take dives to boost his image. He begins to believe the hype and his ego swells, making him feel like a real champion. Polly and Susie resent the deception, and Speed's budding romance with Susie adds to the tension.

Mr. Austin, Burleigh's former boss at Sunflower Milk, buys his boxing contract for $50,000. The arrangement frames Burleigh for a high-profile charity bout against Speed, designed to capitalize on his rising fame. The deal ties his future to the dairy empire.

Socialite Mrs. E. Winthrop LeMoyne organizes the charity fundraiser and the Burleigh–Speed bout. The event is billed as a noble contest, though the fighters' careers were built on rigged contests. Tension grows as the crowd anticipates the showdown.

Minutes before the bout, Speed is knocked out by Burleigh's miniature horse. He is then accidentally given insomnia medicine instead of ammonia and falls asleep during the match, allowing Burleigh to win easily. The victory unsettles the expectations of spectators and participants.

Burleigh is reluctant to retire without a real knockout, but Mrs. LeMoyne inadvertently ends his boxing career by intervening at the moment of truth. The crowd and Burleigh are stunned as the bout concludes in an unplanned retirement. The sudden change forces him to reassess his life and loyalties.

As promised by Mr. Austin, Burleigh is granted a partnership in the dairy company. Speed is appointed as a district manager, marking a new, uneasy alliance between former rivals. Gabby and Spider end up working in milking roles.

Gabby Sloan and Spider shift away from boxing schemes and take positions as milkmen. The transition illustrates a complete reversal from manipulation to everyday labor. The story ends with Burleigh’s life settled in a legitimate business path.

Polly and Susie face a future where show business and performance mix with newly grounded ambitions. They cope with the changes in Burleigh’s career and relationships, choosing paths that align with the more stable life he has chosen. The dynamic among the trio evolves as dreams realign with reality.

The arc closes with Burleigh stepping away from the glamour of boxing into a steady dairy role, having learned humility. The film ends on a note of redemption and the importance of staying true to oneself. The new order sees old schemers recast into ordinary workers, a quiet amends.
