Enthusiastic nature lover Hugh Fearnley-Whittingstall continues his wildlife adventures as he explores the Jurassic Coast to investigate the strange life of its most curious creatures and to meet the local heroes dedicated to helping them. His fascination for marine life centres on an intriguing ocean oddity - the cuttlefish. With the help of local fishermen, Hugh devises a plan to see them close up and to try to understand their otherworldly behaviour.
On the shingle expanse of Chesil Beach, a team of dedicated volunteers keep a 24-hour watch over a colony of little terns to help these rare birds raise their tiny chicks in safety. And Hugh revisits the rockpools he knew as a child in search of new finds and familiar favourites.
