PLOT
Constance, the young widow of a wealthy American, gets a love letter from the Engadine region, signed by the famous guide Toni Anewater she had met during a holiday in the previous year. Constanze and her friend Dorothy therefore go to Switzerland for winter sports. But identical love letters to other ladies in London, Paris and Rome have been sent. Toni does not know anything about the letters. Everything seems to be a cunning of the hotel owner to attract tourists.
