Desc: Sledztwo: Directed by Marek Piestrak. With Tadeusz Borowski, Edmund Fetting, Jerzy Przybylski, Boleslaw Abart. The young Scotland Yard inspector Gregory takes part in the investigation in an unusual case: corpses systematically disappear from the morgues of rural hospitals in the vicinity of London. The circumstances of these incidents are so strange and inexplicable that Gregory can not build a realistic version of events. Outwardly, everything looks as if the dead are resurrected for a while.
