Investigation, at the invitation of the cave's owner, the Marquess of Bath, to see if there is evidence of Palaeolithic human activity in the cave. This may be among the oldest homes in England. The ultimate aim is to get the site scheduled and thus protected from unofficial damage. However it soon becomes clear there is a lot of preparatory work involved. They are joined by palaeontologist Andy Currant, and cave archaeologists Larry Barham and Kate Robson Brown. Caver Malcolm Cotter directs them to a cache of bones; but the tunnel is blocked by sediment from flooding.
