The Plaything of Broadway.

A beautiful young girl, Lola, is a dancer at a private club for wealthy men in New York City. Some of the club members make a bet that Lola can't seduce a young doctor, Jennings. Her attempt fails, and in order to find out why she follows him around and discovers that he runs a clinic on the city's poor Lower East Side. She begins to see the young doctor in a new light, and sets out to help him build the emergency hospital he's always wanted.
