This series it's one of the best I've seen from mexico. It's the story of an ordinary woman who commits a crime and ends up in prison, the character has to adapt in order to survive and becomes a badass. This transformation is amazingly well achieved by the writing and Ana de la Reguera's acting. It's bold series, tough women, violent at times.
I didn't like very much Silvia Carusillo's acting, never believed her character.
