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.
