The plot is a sorta "meeting the parents" approach with lots of suspected secrets and hidden knowledge. A lot of this centres around the character of the son who has ran away when he was I believe nine or ten years old and hasn't been since apparently. As the play progresses we realise the reason the son ran away was because he raped his mother which of course, led to a huge confrontation and he ran away in fear. Pretty twisted but it progresses to get even darker; the mother wants to know her son is still alive despite everything that happened. Every night she sleeps downstairs and allows her son to "break into" the house and rape her again, a way of her knowing that as long as he continues to come back, he's still alive. Pretty twisted.
