Jay, a failed musician, walked out of his family and now earns a living as head bartender in a trendy London pub. Every Wednesday afternoon a woman comes to his house for graphic, almost wordless, sex. One day Jay follows her and finds out about the rest of her life (and that her name is Claire). This eventually disrupts their relationship.
The story follows Jamie, a troubled young man with a birthmark on his face, which has left him feeling isolated and fearful, hiding from the world outside. He lives in the East End of London, an area notorious for its violent hooded gangs. According to news reports, the gangs are now wearing demon masks. But, one night, Jamie discovers the terrifying truth.
