Four teenagers, each facing a major conflict. Majô, the daughter of separated parents, has fallen in love with her mother Raquel’s husband, the teacher Túlio. Caíto, who is gay, lives in a dysfunctional home where his parents' marriage—Dirceu and Marilu’s—is going from bad to worse. Doca is a drug addict, and his sister Bia has become pregnant by her boyfriend, Michel. Their parents, Odilon and Paula, are deeply unhappy as well. Interwoven with their stories is that of Túlio—a former addict turned upstanding teacher—who encounters a haunting figure from his past: his ex-sister-in-law, Fernanda.
