A stripper from a night club is murdered—then, right during the next performance, the second one is killed. But the killer isn’t interested only in the girls: his next victim is the young son of a businessman well known in the city. And the criminal doesn’t stop there—there are more and more victims. Olga Ryazantseva, a specialist in resolving confidential problems, is forced to take on the case, because it directly concerns her boss and patron. Digging through someone else’s underwear is not only unpleasant—it’s also dangerous. Things get especially hot when a visiting hitman gets involved. Who is he—friend or enemy? In the end, Olga faces a choice: die or join the pack of predators. She makes her choice. And then everything falls into place.
