She Couldn't Say No is a 1930 American Pre-Code drama which stars Winnie Lightner, fresh from her success in Gold Diggers of Broadway (1929). It was adapted from a play by Benjamin M. Kaye. An aspiring singer ends up in a love triangle with a gangster and a socialite.

Winnie Harper is a nightclub entertainer. This club is owned by a notorious gangster named Big John. Jerry Casey, a gangster, begins dating Winnie and becomes her manager in an attempt to go straight. Jerry manages to put Winnie in a fancy society nightclub.

Morris, however, falls in love with Iris, a rich customer. In order to be able to buy gifts worthy of his new socialite girlfriend, and also to get money for Winnie's upcoming revue, Jerry asks Big John for another job. Jerry tells Winnie about his love for Iris but she thinks that Iris is not serious about their relationship.

Later on, Jerry gets arrested and Winnie pays his bail, but is broken-hearted when Jerry leaves her to return to Iris.
