Mae West's fourth motion picture, it was based on her original story It Ain't No Sin, which was also to be the film's title until censors objected.

Lamont pressures the Tiger Kid into acting as a robber to "steal back" the jewels; he plans a carriage ride together with Ruby along a dark stretch of waterfront.

The set-up works and a masked Tiger Kid takes Ruby's jewelry and flees, but doesn't recognize her face in the darkness.

She sets a trap by giving Lamont other jewelry for safekeeping, then uses opera glasses to note the safe's combination from a distance.

In the ring, the Tiger Kid puts up a strong fight, but is finally knocked out after thirty rounds, shortly after Lamont had given him a bottle of water.

That evening, Lamont tells Ruby that covering all of the bets will nearly ruin him, and plans instead to set fire to the Sensation House and abscond with the contents of his safe and flee with her to Havana.

The film is noted in the jazz world for being the release of the song "My Old Flame", composed by Arthur Johnston with lyrics by Sam Coslow.

[8] Johnston and Coslow also wrote the songs "My American Beauty", "When a St. Louis Woman Comes Down to New Orleans", and "Troubled Waters" for the film,[3] which also features "The Memphis Blues" and "At Sundown".

[9] However, it received some positive reviews from critics, with Andre Sennwald of The New York Times describing the Johnston and Coslow songs as "quite perfect", and stating that the film was "bolstered by a smart and funny script, an excellent physical production and a generally buoyant comic spirit".
