Un jeu d’enfants

Marianne and Jacques, a young couple from the middle class, reside in a stylish apartment in Paris with their two small children. Their routine is disrupted when Marianne is visited by two unexpected guests, Mr. and Mrs. Worms. These strangers assert that they spent their childhood in the same apartment and request permission to revisit their old home. Marianne consents, but shortly after the enigmatic Worms depart, a series of unexplainable misfortunes begin to unfold.
