Because artist Alberto Giacometti cannot return to Paris after taking a trip to Switzerland during World War II, his brother Diego takes care of his studio all by himself. One day, the next-door neighbor gives animal-loving Diego a tame lady fox as a gift. It is love at first sight. Diego and the fox Mademoiselle Rose spend time with one another and become dear friends during the trials of war. Until Alberto returns when the war is over. Nobody really knows whether Alberto has left the door open to the street on purpose, or not.
