Based on true events.
In the 1970s, Remo and Irmina, militants of the Agrarian Leagues in Chaco, flee military persecution by hiding in the jungles of northeastern Argentina. There, their daughter Marita is born, but the extreme conditions force them to leave her in the care of local peasants.

The secret unravels: the military discover and abduct the child. Faced with tragedy, the couple must confront an impossible choice—risk their lives to recover her or go into exile with the hope of saving her from afar.
