It's November 1988. Col. Jack Knowles (Roy Scheider) is newly assigned to a base in West Germany. He is a hardened warrior frustrated with the lackadaisical attitude of his soldiers. Most want him to relax his intensity as relationship with the Soviet Bloc warms up. He grows angry as a defector is shot dead by men under Czech Col. Valachev (Jürgen Prochnow) right in front of him at the border. He decides to go on his own infiltration mission into enemy territory.
This movie is obviously diffused by real world events. The Berlin Wall literally fell four months before the release of this movie. That's why an opening text was added to place this movie in 1988. The movie retains its logic in that sense but it loses its reality to the audience of its day. There was a few similar cold war thrillers that became out-of-date by the time they got released. It's not their fault but it cannot be discounted.
As for the movie itself, it has great potential as a dive into the psychology of an obsessed warrior but it becomes a clown crossed with Rambo. It's too silly and serious while being unrealistic all at the same time. The only action I truly love is the helicopter landing. The helicopter is hovering around with real intensity like it's going to hit the ground. The movie closes by paraphrasing Albert Einstein, "I do not know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones." It misunderstands the quote by trying to tie it to that final fight. It's obviously an important theme for the movie which makes the flawed understanding a little problematic. All in all, the movie has problems and struggles to compete with real world events.
