Do Vampires Exist?

A taste of Mike's blood sets John on a mission to prove Vampires are real. After folklore expert Dr Juliette Wood tells of undead revenants, the Unexplainers visit the welsh village of Marford. Strange vampire fighting architecture in the village is nothing compared to an even stranger tale of a window tapping vampire bride. To discover more, Mike and John spend a night in an ancient local pub and not only provoke resident vampire entities but somehow end up getting accidentally married.
