One night in 1950 a passenger train runs over a man, who turns out to be the veteran train engineer Władysław Orzechowski, know for his old ways and stern demeanor. As the inquiry panel tries to deduce why would a man like Orzechowski jump in front of a moving train several of the people involved in the case are interrogated, each telling their own version of the story. Can the panel arrive at the truth in a world where workers unite, inferior coal is a badge of honor, and the old order is suspect?
