Maricruz and Beatriz are school friends; Beatriz comes from a well-to-do family, whereas Maricruz belongs to a lower socioeconomic stratum. Both are on the verge of turning fifteen and are preparing to leave childhood behind. Issues within their family and social environments affect them directly; for Beatriz, her parents' marital breakdown becomes the primary obstacle to overcome, compounded by a sexual awakening fraught with taboos and misinformation. Meanwhile, Maricruz must contend with her mother's overprotectiveness and prejudices, as well as the tension caused by a neighbor who is obsessed with her.
