In this film the director's recurring concerns return: the divisions in the Chilean left, and its contradictions between what the director calls the "traditional" and the "revolutionary" left. The problem is exposed through the doubts and obsessions of a strange police chief who cannot establish the limits between critical behavior and militant responsibility.
