For years Time Team fan Frances Davies has been collecting finds from the field outside her back door in Skipsea in East Yorkshire. She has uncovered Neolithic, Roman and Saxon items, but her best finds are medieval pots dating from the Norman Conquest. It's clear that there was some habitation in the area 1,000 years ago, but a geophysics plot of the site reveals incredible results, far beyond the team's expectations. Could Frances have had a whole Norman village in her field, a village lost to the records? And could there be a clue in nearby Skipsea Castle, the seat of power of the Norman overlord of the whole area? The Team have three days to find out.
