A teen with an absentee single mother attempts to accelerate her transition into adulthood with the help of her best friend, and she learns some important lessons about growing up in the process. Ansiedad (Cierra Ramirez) doesn't have a father, and her mother Grace (Eva Mendes) is hardly an inspirational role model. Insulting, inconsiderate, and often too busy with work or men to give her daughter any real attention, Grace is in the midst of an affair with a married doctor (Matthew Modine) when her handsome co-worker (Eugenio Derbez) tries to sweep her off her feet. Meanwhile, Ansiedad begins to grasp the concept of the archetypal "coming-of-age" story in English class with the help of her concerned teacher, Ms. Armstrong (Patricia Arquette), and decides that it's high time she left adolescence behind. Together with her best friend Tavita (Raini Rodriguez), Ansiedad hatches a plan to speed up her development, even if it means willingly sacrificing some of her own innocence along the way. Little does Ansiedad realize that growing up isn't just about getting older, but getting wiser as well.
