Irena and the Shadows (1987)

Costa, a projectionist in a porno cinema, plunges into a dark story of abduction, following a phone call that was not intended for him. Is Mome Pralier dead? Has the ransom been paid? Who killed Baumgartner? What's the doc up to in his clinic? AND SURTOUT - who is Irena? - and how far will she take Costa?.
