Late summer 2007, South of Brazil. Thirteen-year-old Joana needs to unravel a mystery: why had her great-aunt Rosa never dated anyone and ended up dying a virgin at 70 years old? Encouraged by her friend Carolina, Joana starts an investigation about Rosa’s past. Clashing with the conservatism around her, Joana will discover how the women in her family live out their sexuality, while she plunges into her imagination to find her own answers. When rumors start in their small town that Carolina had her first kiss with a girl, the growing intimacy between them disturbs and fascinates Joana.
