In the late 60’s the residents of Zagłębie, Poland, were terrorised by a serial killer who claimed the lives of fourteen women. In 1998 Pieprzyca made a documentary about the events, and now in this film he revisits the subject to tell the story from the perspective of a young detective who is put in charge of bringing the murderer to justice. As the case continues to become more complicated, the need for answers grows and the pressure weighs heavily on him. Pieprzyca won awards for his writing and directing at the Polish Film Festival and Shanghai International Film Festival respectively.
