What could I add more than the other users have already done? They told everything about this authentic gem from Spain, dark, bleak, violent, speaking of a brutal, borderline cop for whom the audience may although feel empathy, no matter the evil side of this character. The first sequences of the killing in the bar are astounding. I won't repeat the scheme, but this could have pleased to Olivier Marchal, William Friedkin or David Ayer. The brutal cop character reminds me the film SHIELD FOR MURDER, starring Edmond O'Brien, made by Howard Koch in the fifties. In the future, I will watch out for further films from this director
