When Moritz learns that the HVA believes the NATO's nuclear war game, Able Archer, is a real attack, he must ask General Edel to pull back before it is too late. As the preparations for NATO's Able Archer manoeuvre intensify, Moritz receives an order from the HVA that cements his fears about the East's paranoia. He has to warn his Western superiors about the misunderstanding. But how? Finally he has no choice than but to blow his own cover—to Edel himself. As a guise to threaten Moritz, Tischbier joins a student demonstration around the Eifel base and encounters Alex, for whom he has bad news. Finally, Moritz races to the border chased by the West German authorities, the only man in West Germany who's trying to escape from the West into the East.
