World War Two has ended a few years earlier and the Cold War is starting when Brett Manning is sent to do some business in Archangel. But on his way, in the thick fog and darkness of the Barents Sea, his ship is run down by a much larger vessel.

Slowly it dawns on Brett and his companion that they now know too much for their own good and that their very lives are in danger. But how do you escape from a ship at sea?
