A docu-noir about thirty years of female murder, documenting the evolution of crime committed by women, in a series of emblematic milestone cases from the early 1940s to the 1970s, using all the material available on the murderers, the victims, the investigations, the trials and, a fundamental issue, the media impact of the crimes and the people involved. An exploration without prejudice about the differences and specificities in the murders observed in the past, but which with time and the profound transformation of society, now seem to vindicate those who say "Women kill for the same reasons as men, and often with the same pain".
