When three twentysomething roommates, living in Edinburgh, Scotland, find a fourth person to share their spacious loft, within days the new lodger is found dead from an overdose. Drugs and large amounts of cash litter the room, and the roommates decide to keep the money for themselves. So they mutilate and bury the body to keep the cops at bay. However, as greed and paranoia overtake the trio's one-time camaraderie, the violence escalates -- this time among themselves.
