There is only one man who knows where enormous sums of money stolen by the SS are kept: Kruger Schtelman. After spending some 25 years in an Eastern European prison, he is to be  released in three days and going to use it for Neo Nazi purposes. The IMF is to find out the whereabouts of the money, knowing that Colonel Sardner, an experienced inquirer, has tried this all the time during Schtelman’s imprisonment. Schtelman did not give the information away and is proud of it. On the day of his release, he's safeguarded out off the country in a van, police cars before and behind it. The car behind is blocked on the road by a truck driven by monks. With a little help the contents of the truck, wooden boxes, are scattered all over and the monks are busy recollecting them. The same happens in front of the van behind the other car. The drivers of each car, believing the other car is directly direct contact with the van, urge the monks (Jim and Paris on one side, two IMF on the other) to hurry up, while Schtelman is drugged and moved. As the monks leave, the drivers become aware that none of them was in direct contact with the van. 

Schtelman wakes up in a submarine. Willy and others are working in a hall arranging the movements of the fake sub and underwater + inside sounds from outside. Schtelman finds a woman in his room who has been tortured. Instead of caring for her, he interrogates her to find out about his own situation. She hardly can speak. Out of the broken sentences he figures out that she broke under the torture and gave away facts about the SS. Herr Rednitz, an SS officer (Paris), intervenes and shows his dislike of the man. In the main room of the sub he also meets rejection and is told that he and the woman, Tracey, will be tried as traitors in the SS headquarters in Scandinavia for having given away information during their imprisonment. Schtelman vows that he wasn’t broken, but he can see that no one believes him. He finds out that Paris is in the SS, but wants to make sure showing him his own SS tattoo. Schtelman wants to see the same at Paris' shoulder. For a moment Paris hesitates, looks at Jim, then shows him the tattoo with his SS number. Back in the other room the woman suffers. Schtelman does not ask the others to give her water nor he offers help; he tries to find out more listening to her weak speaking. She faints. Jim comes in and announces he's dead. When Schtelman touches her neck and still finds the pulse, Jim insists she is dead and has her dumped out into the sea. Schtelman does nothing to stop him. 

Jim and Herr Rednitz maintain a working, not a personal relationship. In the country, the search covers the area cars could have reached in the time they left the place of abduction. Everything is searched closing in around the halls which were just beside the place they’ve stopped the van. Suddenly the sub detects an enemy ship. Schtelman also looks into the underwater monitor just above sea level and sees the ship – a film Willy plays from beside the fake sub. The IMF hit the sub with iron bars and the motors shake the fake sub. Inside they suffer an enemy attack. The are forced to "the ground" unable to go on and at a long distance from the surface. The submarine crew in the lower level try to come up, because the level is filling with water. Jim shuts the exit to their level. To stop the bombardment they decide to take out papers, wood, and anything possible to surface hoping to prove total destruction. Paris suddenly is knocked down by Jim and ends up in the tube filling with water. Without any oxygen and the water rising Paris desperately hits the glass knowing he will die. Jim explains to Schtelman that there is only one evidence which would make the others believe that they are lethally hit. Again Schtelman does nothing to save a life. 

Outside the sub Paris is given a towel and inside the only remaining two people alive get Buoyancy jackets and ready to surface as the ship is gone. If he does not make it, Schtelman will die being known as a traitor. The military in the country come closer. By now they know that no one has left the area, but do not know yet which of the halls it is. Schtelman cannot stand the idea dying as a traitor. Being out of training he knows that his chances to reach the surface alive are slim. When Jim prepares to enter the exit tube, he needs to prove that the money is still at it's place. He repeatedly shouts the bank account number at a totally disinterested Jim. And he keeps on shouting the number after him, while Willy has written it down long ago. Schtelman too enters the exit tube, while the IMF is leaving in the country’s military uniforms. They pass the military, Sardner and others. When "surfaced", Schtelman looks around in disbelieve, faces the military and congratulates them for making him give away the secret. A first baffled Sardner has a desperate laugh.
