Alain Jessua's film explores the twilight between the imagination and the real world. The story concerns a couple who produce comic books for a living: Pierre writes and Jacqueline illustrates. One day fanciful playboy Bob comes along, claiming to live out their comic fantasies. Seduced by Bob's millions, Pierre and Jacqueline accept his invitation to his Swiss chateau. Fantasy soon becomes reality, as Pierre starts to use Bob's lifestyle as inspiration for a new comic strip. Before long, the boundaries between comic book and life are fading out of view and life is becoming deadly serious.
