Cabaret(1927)

Gloria Trask, who has risen from a squalid East Side environment to stardom in Costigan's nightclub, is admired by Tom Westcott, detective, and Sam Roberts, a gangster with whom her brother is involved. Andy, threatened by the gang, is forced to pay off, and in a showdown in Gloria's dressing room, Andy shoots Roberts in self-defense. Gloria helps her brother to leave on a South American liner, while Tom forces Roberts' girlfriend Blanche to admit to witnessing the crime. Blanche insists that it was murder, but Tom forces her to admit that Roberts had a gun by accusing her of the killing.
