After a ten-year absence, Severino returns to his tribe, the Manzeneros, who live on the edge of the Argentinian Andes. The reason for his visit is to take his younger brother back with him up north. However, in his home village, Severino finds a tense and troubled situation. His father Raymundo has recently been found dead. He was on the tracks of a gang of white bandits who had stolen cattle from both Indians and settlers. A sheep breeding company is behind these criminal machinations. This company seeks to drive the Indians and settlers off the fertile land so that they can purchase it cheaply.
