Telefon is a 1977 spy film, starring Charles Bronson, Donald Pleasence and Lee Remick, and was directed by noted action-film director Don Siegel. The film is based on a 1975 novel about mind control by Walter Wager. C During the Cold War of the 1950s, the Soviet Union planted a number of long-term, deep-cover sleeper agents all over the United States, spies so thoroughly brainwashed that even they didn't know they were agents; they could only be activated by a special code phrase (a line from Robert Frost's poem "Stopping by Woods on a Snowy Evening" followed by their real given names). Their mission was to sabotage crucial parts of the civil and military infrastructure as a precursor to a possible US/USSR active conflict or war.
Over twenty years pass, and the Cold War gradually gives way to détente. Nikolai Dalchimsky (Donald Pleasence), a rogue KGB officer, defects to America, taking with him the Telefon Book, which contains the names, addresses and telephone numbers of all the agents. He starts activating them one by one. American counterintelligence is thrown into confusion when seemingly-ordinary citizens start blowing up what are, in some cases, long-abandoned facilities and commit suicide right afterwards.
