Dean and Sam Winchester were raised as Hunters by their widowed father, seeking vengeance on the supernatural elements that took their mother from them. But the road to vengeance is a dark one, and is it a place where children can have any semblance of a life? On an academic break while at Stanford, Sam Winchester visits the United Kingdom on what is meant to be a sleepy trip. His first day he meets the hypnotic 'Emma of the Isles,' who takes him to a nasty part of town, where an even nastier evil lurks. This could be the very first team-up between European and American Hunters – but will it end in disaster?
