The Eloi family, who have just won the "model family" competition, set off for winter sports. Also on the trip are Aunt Gabrielle and Dagobert, the village warden. For the eccentric little group, the initiation to the joys of skiing begins with a lot of excitement. The vacation gets complicated when a Hindu prince has a precious diamond stolen from the local hotel.
