Dan travels to the Scilly Isles to tell the tragic tale of Admiral Sir Cloudesley Shovell and the 1707 naval disaster off the Isles of Scilly that caused a staggering loss of over 2000 men. Dan ventures out to the place where the ship went down to see this dangerous stretch of sea for himself. He discovers how this catastrophe spurred advancements in navigation and the quest to solve the problem of longitude.
