Two policemen— Katya and her partner Kukharenko, find a strange man with a canvas bag on his head at a bus stop. His name is Roma Aksentiev. Before that, he had been in the hospital for six months, but the 30-year-old man remembers absolutely nothing more: where he lives, where his relatives are, what happened before the hospital. Aksentiev has a gift: as soon as he touches the hands of a man or a woman, he sees their past or future. Such psychic abilities can be useful to police officers, especially since right now a mysterious maniac named Vodyanoi appears in a provincial town. He drowns his victims in reservoirs. A mystical detective will reveal the secrets of Aksentiev's gift and past, and the psychic himself will help Katya and her partner solve more than one complicated case.
