Mum & Dad (2008) Mum and Dad, and their adopted children, Birdie & Elbie, work at the airport. The family live off whatever they scavenge from cargo holds, offices and hotels including a steady stream of transient workers who populate the airports soulless hub. When Lena, a young Polish office cleaner, is befriended by Birdie, she gets drawn into a nightmarish world of torture, murder and perversity. Imprisoned in a suburban House of Horrors and designated a Mummys Girl, Lenas only options appear to be to become part of the family and join them in their insanity or die.
