An American agent working with the British is assigned to Berlin to ferret out a treacherous neo-Nazi gang. The last two men given this job have already been killed and the agent soon realizes he can't trust anyone, not even the people on his own side.
George Segal, Alec Guinness and Max von Sydow square off against each other in this espionage thriller, adapted by Harold Pinter, from the novel by Adam Hall, aka for writer Elleston Trevor. Ace spy Quiller is lured away from holiday to replace a British agent who died while essaying a most challenging assignment: infiltrating the Neo-Nazi ranks. Now Quiller must find the group's station in Germany. Along the way, however, he is abducted, tortured, reprogrammed, doped and almost blown up. The resilient prober, though, will show the evil Neo-Nazi leader Oktober that he has more lives than a cat and more tricks up his sleeve than anyone this side of James Bond.
Source writer "Adam Hall" is actually a pseudonym for novelist Elleston Trevor.
