Buenos Aires. 1976. In the heat of summer, the Ferrero family escapes to the lush expanse of Tigre. Osvaldo, a distinguished doctor, and his wife Yolanda, gather with their daughters, sensible Julieta who lives in Miami, and willful Graciela - nineteen, and madly in love with her fiancé, José. Those days will be the last the family ever spends together. On their return to Buenos Aires, the Argentine military stages a coup. Friends and colleagues disappear overnight, and Osvaldo is forced to flee to Europe. When José is abducted, Graciela goes into hiding, then vanishes in turn. Osvaldo can only witness the disintegration of his family from afar, while Yolanda fights on the ground for some trace of their beloved daughter. Soon she realizes they may be fighting for an unknown grandchild as well.
