After returning from Mars, the Mercenaries relax and do some fishing. They retell the stories of how they came to join the French Foreign Legion, but are soon captured by the Foreign Legion as deserters. The Legion gives them a mission to fulfill to avoid the firing squad. The Mercenaries are sent to Norway to recover a fully-intact Viking ship that has been preserved encased in ice. As they free it from the ice, terrorists attack to claim it as their own.
