Plot Summary:Mariposa, a wild dancer in a cheap Seville cafe, is taken to New York by Señor Sprott, a prominent theatrical producer. Billed as \"The Charmer,\" Mariposa becomes the toast of two continents. Among her most ardent admirers are millionaire playboy Ralph Bayne and his chauffeur Dan Murray, who both first met her in Spain. Madly in love with Bayne, Mrs. Sedgwick invites Mariposa and her mother to a weekend party in a deliberate attempt to humiliate the beautiful dancer. Bayne quickly realizes that Mariposa is out of place in high society, and, determining to make her his mistress, takes her home with him. Mrs. Sedgwick unexpectedly arrives at Bayne's swank suite (followed by her suspicious husband), and Mariposa protects the society woman's reputation at the cost of her own. Murray arrives and attempts at gunpoint to force Bayne to marry Mariposa, but Mariposa objects and declares her intention of marrying Murray instead.
