In the deep snowy forests of Sweden, Vincent Minnelli, a doctor, mistook a girl for an antelope and shot her while he was hunting. The girl he shot, Joana, was unharmed, but she told Vincent a shocking story, and the next morning she disappeared without a trace. Instead, he was visited by an emissary of General Ambrose du Closter, the head of the castle of Scorchloster, a mansion on the shores of a lake.

General Closter was interested in Vincent's books and research and wanted to invite him to his mansion. Vincent went to the house as requested and was introduced to his daughter, Mona Lisa, by the general.

To Vincent's surprise, Mona Lisa is a duplicate of Joanna. Vincent thought they were the same person, but Mona Lisa told him that she had never met Vincent.
