Sunny Side Up (1929)

Molly and Bee, sweet young 'working girls,' live in a cheap room over a New York grocery store. Molly's idol, wealthy Jack Cromwell, lives in a Long Island mansion but is markedly less happy, since his fiancée Jane won't discourage her other admirers. Fleeing in his car, Jack ends up in an urban block party where he meets you-know-who.
