When Ben (Liam Boyle, SKINS) witnesses a mentally disturbed man by the canal-side throwing a suitcase into the water, his curiosity gets the better of him. After fishing the bag from the oily depths, to his horror upon opening the bag, he discovers a 15 foot long African Rock Python inside. Despite his various attempts to get rid of the creature, it soon becomes clear that the animal is going nowhere. When his neighbour’s Chihuahua disappears and other strange events begin to occur within his building, Ben realises that he has a supernatural creature at his disposal. A creature who has chosen him, and will guide his descent into a darker world.
