2029. In Brazil, poor and black children are marked at birth with an ankle bracelet and have their lives traced because it is assumed that they will, sooner or later, go into crime.

Berenice is a dedicated female taxi driver in Rio de Janeiro. She is consumed by her job and the little free time she has needs to be divided between raising her son Thiago, a teenager exploring his sexuality, and her troubled relationship with her husband Domingos, a police reporter. The scars of the worn-out relationship, ruined by her husband's violent outbursts, have erased her femininity and led her into a great existential emptiness. The murder of Isabelle, a beautiful transgender woman, on Copacabana Beach, ignites her investigative side and transforms her life.
