Ruby Carter (Mae West), the night club sensation of St. Louis, relocates to New Orleans and becomes the prize attraction of "The Sensation Club." West's risque brand of humor and naughty musical numbers enliven a plot that involves jewel thieves, a fixed boxing match and murder. Directed by comedy expert Leo McCarey (Duck Soup, 1933, The Awful Truth, 1937) and featuring Duke Ellington and His Orchestra who provide musical accompaniment for several of West's songs.
