A coming of age story about two young teenagers in the violent market neighborhood of Tepito, Mexico City. Nacho is a sweet boy, but his dysfunctional family and social setting threaten to turn him into a criminal. Neglect and abuse run rampant in his household, which is why the smart and entrepreneurial 13-year-old spends much of his time with Cacayo, a kind but dim-witted man who pirates movies for a living. When Nacho meets Mayra, the daughter of a local drug lord named La Diabla, he falls head over heels in love, despite the obvious danger.
