After another "successful" case of catching a thief, Mukhich and Kristina are fired, and they open their own detective agency in Barvikha. The partners take on a variety of cases: from spying on the mistress of a rich entrepreneur to protecting the director of an IT company, into whose consciousness someone is trying to penetrate in a dream. Mukhich and Kristina will do everything to ensure that no crime in Barvikha remains unsolved, and old acquaintances will help them in their investigations.
Artyom, a young adventurer, meets Felix - the once legendary art thief, who was called "Number One". The "Old School" and the newcomer decide to crank up the scam of the century - to steal one of the most expensive paintings of our time - "N 1" by Mark Rothko from the gallery owned by the ex-wife of Felix and her new husband. By chance, Artem meets Marina and falls in love with her. And she turns out to be an investigator and really wants to catch Felix red-handed.
