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.

On the seventh birthday of a child who lives with their perfect family in a doll house but doesn't fit into conventional gender norms, the social pressure imposed by their traditional family is so suffocating that the only way to escape is to make the magical birthday wish, before blowing out the candle on the cake.
