Rio de Janeiro, 1950. In the conservative Portuguese household of the Gusmão family, Eurídice, 18, and Guida, 20, are two inseparable sisters who find in each other a safe space for their hopes and aspirations. While Guida has in her little sister a trustful confidante for her romantic adventures, Eurídice finds her spirited older sister the encouragement she needs to pursue her dream of becoming a professional pianist. Until one day, fed up with living under the strict rules of their father, Manoel, Guida embarks on a whirlwind romance with a handsome sailor and elopes to Greece. When she returns months later, pregnant and single, Manoel brutally banishes her from the home and tells her that Eurídice has left to study music in Vienna and doesn’t want any further contact with her.

Among the daily hardships, the greatest battle is against the fate that separated them. Will they find each other in time to overcome the oppression that suffocates them?
