 Based on a story by Argentine literary icon, Jorge Luis Borges, the film follows the parallel lives of two brothers of Danish ancestry in the "Pampas" of the Brazilian-Argentine-Uruguayan rural area. The rough life these "gauchos" (South American cowboys) lead means they must share all aspects of their lives. Suddenly, enter "A Intrusa" (the Intruder), played by the Brazilian actress Maria Zilda. How is this new element in their lives to be shared?
