Ghostboat is a 2006 British television film based on a novel by George E. Simpson and Neal R. Burger starring David Jason – a fantasy tale of His Majesty's Submarine Scorpion vanishing during the Second World War leaving only one crew member (David Jason) surviving. 38 years later in the Cold War year 1981, the Scorpion reappears; the crew have disappeared, but the vessel is otherwise unchanged and has not aged in the intervening years. A Royal Navy crew along with the sole survivor of the original voyage is given the mission of retracing the last days of the boat prior to its 1943 disappearance. A supernatural influence takes hold of most of the crew, and they start showing characteristics of the old crew. They find themselves fighting Second World War ghosts.
