Invisible Stripes is a 1939 Warner Bros. crime film starring George Raft as a gangster unable to go straight after returning home from prison.

The movie was directed by Lloyd Bacon and also features William Holden, Jane Bryan and Humphrey Bogart.

The screenplay by Warren Duff was based on the novel of the same title by Warden Lewis E. Lawes, a fervent crusader for prison reform, as adapted by Jonathan Finn.

Cliff's younger brother Tim is worried and increasingly disillusioned because he cannot afford to marry his girlfriend Peggy and fears he will not be able to honestly find a position for himself in the world.

Afraid that Tim might end up leading a life of crime like himself, Cliff decides to help him find the money to settle down.

There are no jute mill scenes, no bullying guards, no big prison break sequence; in fact, we don't understand why they've suddenly commuted our sentence from the customary duration of the picture to a brief prison prelude, a mere graduating exercise at the beginning: good behavior, maybe.
