This is the device that gives us a glimpse of the ethics, games, esthetics and eroticism of these girl-women. It is not easy to say what the subject is, there are so many: the discovery of sexuality, discrimination, chance, drugs, maternity, traditions, betrayals, power, love. A mural of a complex reality from the point of view of twenty-something women in the skin of 14 to 15 year old girls.

Sara is a woman who was sexually abused and has been in pain ever since. Now, she has only one goal: to take revenge on every man who crosses his path, no matter what his intention is.

Brenda and Sara manage to escape from prison and return to the neighborhood to start a business and, with the help of El Sapo, open another elite whorehouse, which protects a very powerful person.

Brenda and Sara are the most powerful women in Mexicali and they will do whatever it takes to maintain power no matter the consequences. A story full of action and eroticism that reflects today's society where the political class is involved with criminal groups to perpetuate themselves in power.
