In 1963, archaeologists discovered a mysterious pit full of human bones in Wharram Percy, a preserved medieval village in Yorkshire. Some were dismembered, some were burnt, and all were buried here for a specific reason. Now, our hosts dig through old records and use the latest forensic technology to determine if these corpses were killed in battle, were the result of human sacrifice or cannibalism, or were mutilated to stop them from coming back from the dead. Clive Anderson and Mary-Ann Ochota humorously unravel Yorkshire's 'living dead' - human remains from the Middle Ages, when it was believed zombies walked England's green and pleasant land.
