A high-tech, action-packed deep sea thriller. During World War II, the British destroyer H.M.S. Edinburgh, loaded with gold, was sunk deep in Artic waters by the Germans. Forty years later, a salvage operation begins, and with it a nightmare of piracy, high-seas murder, and the kind of political tension that threatens a superpower war. One man, ex-Navy diver Will Altman, must survive the dangers above to discover the secret below.
