Everything in life has an A side and a B side

Durval and his mother Carmita live at the back of a record store they own in São Paulo specializing in vinyl records. They lead a boring and unattractive life, until the day Durval hires a maid, Celia, to help his mother with the housekeeping. However, on her second day, Celia goes away leaving a 5-year-old child behind, Kiki, and a note promising to be back in a couple of days. Durval and Celia are charmed by the child at first, but soon they see some sad news about Celia and Kiki on TV that change the whole situation.
