The team's journey continues around the stunning shores of Devon and Cornwall. Nick Crane is on a fishing expedition on board one of the last remaining Brixham trawlers. He also explores how Henry VIII, fearing attack after his famous divorce, built a string of cleverly positioned forts all along the south coast. The Isles of Scilly are surrounded by lush, golden green underwater meadows of seagrass; Miranda Krestovnikoff explores the diverse wildlife of this natural sub-sea paradise. Mark Horton reveals the extraordinary story of how Lawrence of Arabia went to Plymouth, where he helped develop revolutionary fast rescue boats that saved countless lives in the Second World War. Dick Strawbridge learns the surprising secrets of the global steam power revolution pioneered in the tin mines of Cornwall some 200 years ago. And with the aid of some big wind machines, Alice Roberts creates her own perfect storm.
