Policeman Leon Kramer (Vogel) and his partner Pit (Sözer) are observing two people in a car.

When Leon goes to fetch some coffee, the two people in the car and Pit are killed.

He learns that one of the two people he observed is an ex-Red Army Faction terrorist and the other is his former lawyer.

A friend of the lawyer (Berricke) contacts Leon and gives him information about the RAF.

Leon learns that there may be a conspiracy among important people in the government using terrorist groups for their own purposes.
