Le Beau Monde (1981)

Jean Pierre, a young Parisian salesman, decides to go on vacation by hitchhiking at random. Taken as a jaguar by a rich man, he finds himself invited to his villa in Saint Tropez and discovers a luxurious, idle and decadent universe. A tasty TV movie, written and directed by Michel Polac, with a very young Fabrice Luchini.
