Forbidden is a 1932 American pre-Code melodrama film directed by Frank Capra and starring Barbara Stanwyck, Adolphe Menjou, and Ralph Bellamy.

An original story inspired by the 1931 novel Back Street by Fannie Hurst, with a screenplay by Jo Swerling, the film is about a young librarian who falls in love with a married man while on a sea cruise.

Frustrated by her loneliness, she withdraws her life savings and buys a ticket for a two week romantic cruise to Havana— advertised as the "land of romance".

In Havana, they spend their time together gambling, drinking, riding horses, and taking moonlit walks on the beach.

She takes a job as a clerical assistant for the Daily Record newspaper, where she is pursued by brash reporter Al Holland.

Their merriment is interrupted by a phone call from Al, whose marriage proposal to Lulu prompts Bob to confess that he is married to an invalid wife whom he cannot abandon.

Bob adopts Roberta, taking her home the next day to present to his wife, Helen, who has just returned from a health cure in Vienna.

She leaves him and their child because she cannot bear living in his household— watching Helen be the mother to her daughter, and the wife to the man she loves.

After he dies, however, Lulu tears up the will and throws it away, in order to protect Bob's memory and their daughter Roberta, who is engaged to be married.
