Host Clive Anderson and Mary-Ann Ochota are on a trip through time and across the U.K. to examine the sacred sites, supernatural beliefs, and strange rituals of the ancient Britons. Their journey will take them from Ice Age shamanism treasure troves to Stone Age mysteries like the Rollright Stones and Stonehenge to Iron Age tales of human sacrifice to Middle Age zombies and witches. It's a wild 10,000-year trip to uncover the lives and beliefs of our distant ancestors from the unsettling to the utterly surprising.
