In the summer of 1968, terrifying events occurred in a small northern town of Ozyorsk. A body of a sixteen-year-old girl was found in the river, with a carved star on her back. The question of who could have committed such a cruelty remained open: it could have been former fascist prisoners of war or brutal criminals. Prosecutor Vladimir Alutfeev and investigator Sergey Penkin began the investigation with the sports camp coach, who was suspected of molesting the girls. Also under suspicion was a local eccentric, whose home search uncovered dolls with gouged-out eyes and drawn stars. But both versions were soon rejected, because a new murder of a teenage girl occurred—exactly repeating the first.
