When Alain and Marie view a house in a quiet suburb, the realtor gives them a warning: the hatch in the basement will change their lives completely. That is not too much to say: after their first experience in the basement they immediately decide to buy the house. Because what happens behind the hatch in the basement is incredible (but true!).

Director Quentin Dupieux (Réalité, Deerskin, Mandibules), king of absurdist cinema, seems to have an inexhaustible stream of bizarre ideas. In no time at all he made Incroyable mais vrai (unbelievable but true) and his next film, Fumer fait tousser (smoking makes you cough), is also ready.
