This is the first of the two movies directed by highly talented actor Charles Vanel. The first part depicts in parallel a wedding and the miners' work.;it's nice to watch but needless to say,it's the second part which sustains the movie. Vanel creates a disturbing frightening atmosphere with two masked men ,one of whom was disfigured after an accident;And the final unexpected twist ,at a time when they were not that common,packs a real wallop.
