"SMERSH. Prodolzhenie" is a military spy detective, a sequel to the Russian series set during World War II. A new member joins the Soviet security team - Konstantin Lavrov, the son of a diplomat. He is a bold and daring young man who is quick on his feet, fluent in multiple languages, and relies on intelligence rather than brute force in his work. Experienced counterintelligence officer Pavel Semenov will have to make room for him and work together as a team. Their new mission is to neutralize a German saboteur.
