Third in a nine-part series of individual documentaries from a variety of new and experienced directors.

Deep in the Gulf of Suez lies the wreck of the SS Thistlegorm. A merchant ship, it was on its way to North Africa when it was sunk by German bombers in 1941. Nine of the crew died on that moonlit night. This film tells the story of the death of the ship, tracks down the remaining survivors, returns to the site of the wreck, and dives to the seabed to discover an underwater world full of ghosts and the wreckage of a fantastic military cargo.
