Hopelessly in love, young aristocrat Octave seeks the help of a magician to exchange bodies with his beloved's husband. But his inability to speak her native language soon estranges him from 'his' wife, while the real husband, stuck in Octave's body, is out for revenge. Based on a story by Théophile Gautier.
