A hooded, disfigured young man is eating at a diner, being watched by a stranger. The stranger is Wyburd (Clive Russell), who has been stalking the young man, Simon (Jonas Armstrong). Wyburd convinces Simon to join him in his truck, where Simon passes out and awakens strapped to a table. Wyburd offers him a choice: a slow death, or a quick and clean death by telling the story of the Book of Blood, a series of scars and inscriptions carved on Simon from head to toe. Opting for a clean death, Simon reveals his story.
