Rob is watching a tape on serial killer Ray Hineman who describes his need to kill and the gift God gave him; which is both freedom and a triangle tattoo. When Rob's mom walks in and gives him every reason to kill her, the act escalates his blood thirst and sends him through a spiral of madness and murder. But, what is this triangle God gives? Why does his neighbourhood only exist in the darkness? And why are all his neighbours just as insane as he is?
