Her uncle, General Strizhak, arranges a niece to assist police major Oleg Mishchenko, who was just investigating the death of her last dead patient. One of the first cases in which Inga is involved is about the persecution of the famous actress Mary Dest.

The case takes a completely different turn when they discover Mara dead ... Meanwhile, the unknown herself begins to pursue Ingu herself - sends her presents, calls ...

Ingu is disturbed by her pursuer. She seeks help from her US friend Dan Morgan. Meanwhile, the media recalls the story of Inga a year ago, when her patients died, as well as the case of the disappearance of her fiancé Jerry, who disappeared under mysterious circumstances two years ago ...
