Russian detectives unwind the ball of the most intricate and cruel crimes. They are consummate professionals, the best cops in town. Even on the most dangerous missions, this quartet never loses their sense of humor. It is it that helps them find the most incredible ways out of any situation. They uphold the law and emerge victorious.

In the center of the plot is a senior investigator named Masha Shvetsova and her male colleagues. The plot is the most vital, but, like in “Streets of Broken Lanterns,” it is seasoned with a fair amount of humor - otherwise, how can the audience (and the heroes) endure countless morgues, identifications and other “cute” charms of the investigative routine?

The life of a successful lawyer and law academy teacher Marta Orlova is changing dramatically in just one day. She finds out that Artyom's fiance and colleague is cheating with her student, and her stepfather, the head of Martha's firm, who raised her after her mother's death, takes Artyom's side, because Martha's marriage to the son of Justice General Nikolsky is beneficial to both families. Finding herself without support and the opportunity to continue working with her stepfather and Artyom, Marta decides to open her own law firm, the main profile of which is helping people who are unable to pay for the services of a lawyer on their own.

It shows the life of a man who lost his memory after a car accident. It's like a person is being reborn. But the new life does not bring happiness to the hero. Well-mannered, with good manners, he asks his friend, "What kind of person was I?" And gets an answer: "You were a heavy drinker." All the hero's attempts to establish contact with the world around him end in failure, and the final scene is very dramatic.
