A science fiction film in which a young man (Romain Duris) ends up in a futuristic version of Paris after a millennium party, where he meets a seventy-year-old man (Jean-Paul Belmondo) who claims to be his son.

In this UFO of a film, the existential stakes of science fiction meet the everyday squabbles of the French comedy-drama. Set and shot at the turn of the millennium, this fun reflection on the sweet aimlessness of youth and the weight of adult responsibilities channels the chaotic Y2K atmosphere.
