Separation City (2009)

After the birth of two children Simon's (Joel Edgerton) marriage to Pam (Danielle Cormack) is becoming a bore in which the only climactic feelings he has involve an unfortunate new tendency for premature ejaculation. He develops an interest in another young mother, Katrien (Rhona Mitra), whose husband Klaus has been cheating on her. The world of young married parents in Wellington is fast leading to a whole new breed of men: the men of 'Separation City'.
