In a solitary town nestled in the Mexican mountains, the girls wear boyish haircuts and have hiding places underground. Ana and her two best friends take over the houses of those who have fled and dress up as women when no one is watching.

But one day, one of the girls doesn’t make it to her hideout in time.
