This documentary tells a part of the forgotten history of the Mbya Guaraní people who ancestrally inhabited the basin and islands of the southern Paraná in Paraguay and Argentina (Departments of Itapúa and Misiones). In the 80's, they were exiled from their lands without consultation or compensation, violating international treaties, for the construction of the Yacyreta (EBY) binational hydroelectric plant in Paraguay and Argentina. Similar situation lived other members of this town in nearby regions, affected by the colonization of the Paraná riverbank, ending all cornered in small communities. The displaced tell their story, and tour their ancient Tekoha, their sacred places, to which they do not have access today because they have become the property of EBY or private estates. Survivors originating from these lands are currently demanding compensation for the granting of the last Itapúa forests for native peoples, so that they can be protected, as a national park.
