Work is in full swing on a remote island in a holiday home, where the team is called to investigate the drowning of a young violinist. It looks like a quiet family place, but it soon turns out that almost everyone in this place is hiding something from the owner of the house. Polina tries to solve the crime by relying on her visions, which point to an old, unsolved tragedy. And he decides to take a desperate step - to confess his secret to Maxim. But the most shocking discovery awaits the team at the end, when a certain woman appears on the threshold of the police station.

Investigating the brutal murder of a woman who was trying to change her life, Polina and Igor enter into a secret business selling lethal pills. To find the killer, Polina will have to play the role of a desperate client and look into the very heart of the cult of slimness, where the "best version of herself" can cost her life. At this time, Polina's life splits in two. Her sister, being under hypnosis, uses her gift for the benefit of the savior. And the man whom Polina considered a traitor appears on the doorstep with a shocking statement: he was framed.
