Something terrible is happening in class 3A at Calmecatl Junior High. No one can leave the classroom until the guilty party is found. 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.
