Michel Mortez travels around France hosting a radio game show he created 25 years ago. He is famous among the average Frenchmen. Rivetot, his assistant and technician, always goes with him. He is the only one who knows what really lies under Mortez's appearance of a playful don Juan. When the program is canceled, Rivetot delays telling Mortez as long as possible... Both malicious and tender, this bitter comedy also shows nostalgia.
