De Passievrucht

Armin is in crisis. One fateful day he discovers he is infertile and has been throughout his life. From this he discovers his first wife, Monika was unfaithful before she died, how else could she have had the child that Armin thought was always his. His paranoia drives him to find the truth and in turn pushes those closest to him further away, particularly his now teenage son, Bo. But Armin is unprepared just how deep those closest to him are involved. (imdb)
