Soviet Union planted long-term, deep-cover sleeper agents all over the United States. They were brainwashed so even they did not know they were agents and can be activated only by a special code phrase. More than 20 years pass, and the Cold War gradually gives way to détente. A rogue KGB clerk travels to America, taking with him the names, addresses and telephone numbers of all the sleeper agents. He starts activating them, one by one. American counterintelligence is thrown into confusion.
