In 1981, former Colonel Pavel Bugrovsky escapes from a prison colony in Siberia, where he served a life sentence for spying in favor of Western special services. He has information about Soviet agents abroad, including the name of a new FBI employee. Major of the KGB Oleg Kamorin is tasked with finding and neutralizing Bugrovsky, who might pass information to his handlers. The enemy is cold-blooded and confident in his victory, but he doesn’t account for the experienced Soviet counterintelligence agents standing in his way.
