Hot summer of year 1992. The world has seen the Communist Regime in Czechoslovakia fall. This is what happens to detective Richard Krauz (played by Maciej Stuhr, the son of legendary Polish actor Jerzy Stuhr), when he is handed a case of a mysterious body, found in the course of the reconstruction of a cemetery. The body has a nail stuck in its skull, indicating the person did not go silently into the night. Richard wants to keep it ethical, but once he discovers that communist secret police was behind the torturing and the particular body is a sexton, related to a history of blackmailing crimes committed on priests, he soon finds himself on a slippery slope as the trail leads to an expert on interrogations within the communist secret police, the so-called "Red Captain".—Maria Reinup
