When recently widowed vaudeville performer Florette Faxon marries acrobat Hap Stanley, her son Jimmy takes an instant dislike to his new stepfather, preferring the company of happy-go-lucky vaudeville comic Bud Hannigan.

Paramount's You Belong to Me is a showcase for juvenile performer David Jack Holt.. The boy is cast as Jimmy Faxon, the son of recently widowed vaudeville performer Florette Faxon (Helen Mack). When Florette marries acrobat Hap Stanley (Arthur Pierson), Jimmy takes an instant dislike to his new stepfather, preferring the company of happy-go-lucky vaudeville comic Bud Hannigan (Lee Tracy). Though Bud tries to encourage Jimmy to give Hap a chance, it turns out that the kid's instincts are correct: Hap is a philandering heel, who walks out on Florette at the earliest opportunity. The upshot of all this is that poor Jimmy is left an orphan, with old reliable Bud providing the boy with a shoulder to cry on at the fade-out. Helen Morgan adds to the overall gloominess with one of her patented torch songs.
