With little else to help him beyond sharp wits, a strong will and a very dedicated schoolteacher, American spy Quiller (Segal) combs West Berlin for the headquarters of a shadowy neo-Nazi movement. Closing in on one disturbing truth, he quickly learns another: he is not the pursuer, but the prey - in a rapidly closing trap!
