Rio de Janeiro, Brazil, 1950. In the conservative home of the Gusmão family, Eurídice and Guida are two inseparable sisters who support each other. While Guida can share with her younger sister the details of her romantic adventures, Eurídice finds in her older sister the encouragement she needs to pursue her dream of becoming a professional pianist.
Kept apart by a terrible lie and a conservative society, two sisters born in Rio de Janeiro make their way through life each believing the other is living out her dreams half a world away.
