Miss Shumway Goes West (1963)

Journalist Milan finds Myra, the daughter of the Circus King, who had gone to South America to satisfy her taste for the marvelous. The latter uses her gift of doubling herself, which was transmitted to her by an Indian, but her bad double goes to Europe to receive the 30 million that the King of the Circus was going to offer as a reward to the one who found his daughter. The good double remains, for his part, with Milan.
