As a favour to a friend, The Collectors become interested in the story of the lost trains of Thessalonica. The trains are discovered but the trail leads them to a ship sunk by the Royal Navy at the end of World War II.
Petros hires a salvage team to find the wreck. The Cosa Nostra, a criminal syndicate in Sicily, plan to steal whatever they recover.
With their lives at risk, it becomes obvious The Collectors and the salvage team must fight and defeat the Cosa Nostra to survive.
