Time Team officially returns for its first brand new episode in a decade. New presenters Dr Gus Casely-Hayford and Natalie Haynes join team members old and new to investigate an Iron Age settlement in Cornwall with mysterious underground passages, known as a fogou. Armed with new technology, and with help from Site Director James Gossip and the Meneage Archaeology Group, Time Team have just three days to shed light on this fascinating prehistoric site on the Lizard Peninsula. Can they do it?
