After another "successful" case to catch the thief, Mukhich and Kristina are fired, and they open their own detective agency in Barvikha. Partners take on a variety of things: from spying on the mistress of a wealthy entrepreneur to protecting the director of an IT company, whose mind someone is trying to penetrate in a dream. Mukhich and Kristina will do everything so that not a single crime in Barvikha remains unsolved, and old acquaintances will help them in their investigations.
