There’s a number of boats with bodies of young women whose bodies are covered with water lilies found on the lakes around a little town near Poltava. The police assume it’s been done by a maniac, but they fail to catch anyone. The locals are terrified – a legend says there’s the ghost of the drowned bride dwelling on the lakes that kills young women. A special investigator Oksana Bila, who specializes in searching for serial killers, is sent from Kyiv to investigate the case. However, nobody knows that Oksana has her own personal interest in the case of the dead lilies.
