The body of a young woman washed up by the sea on the beach of Tri-Cities. The abnormal trauma on the victim suggested that it was a murder. The investigation is led by the ambitious and indomitable prosecutor Leopold Bilski(Jakuo Park Gelshou), and also involves the victim's mother and judge Helena Bogucka(Maya Ostazeska). All clues point to a seaside nightclub that is inextricably linked to a female murder 15 years ago. The information collected from the investigation and the evidence that has been concealed over the years have gradually lifted the dark veil of crime in the three cities. Bilski and Bogucka's discovery began to make local police very difficult.
