When I was a High School student, I learned that nothing can modify its status of repose or movement without a cause. Recalling that I tried understand why a killer suddenly repent of "all his sins" and become a "good guy"... Allegedly, the manichaeism approach of this film is the only reason that a man looking to a mother holding her baby (an allusion of the medieval portrait of the Holy Virgin?) make up his mind so quickly... I made this short beginning in order to justify a consideration about the plot: Well, the plot is very singular and leads us to several ways until the surprising dead end. The actors are well conducted by the hands of the director apprehending our attention until the final.
