Sixty-eight-year-old Simona Peková, a star of Brno's HaDivadlo, gives an exceptional performance in this blackened comedy about the monsters in and around us. When a couple of thirty-somethings let the mother of one of them cross the threshold, they have no idea that he has just found himself in a chamber purgatory.
