Little Miss Broadway (1947)

Judy Gibson Jean Porter), upon leaving finishing school, goes to meet her relatives, whom she believes to be wealthy and socially prominent. Actually, there are penniless Broadway characters and, in order to avoid Judy learning the truth, they take possession of a Long Island mansion owned by a thief presently doing time in Sing Sing. Judy arrives with her fiancé Dick Nichols (John Shelton) and his father, an industrialist who tries to sell worthless stock to Judy's family in order to bolster his shaky financial status. They give him $200,000, part of the stashed loot they found belonging to the home-owner thief. The latter escapes from prison. Complications arise. Jerry Wald (Jerry Wald) and his band provide music for Jean Porter's singing, and pert-'n-pretty Porter, as usual, carries the show.
