The life of the gaucho Juan Moreira, his fall into crime, persecution and death.

The romance between an actress and a young man provokes the rejection of the class to which he belongs.

The film deals with the conflict between a father, master of a cattle ranch, and his son, who has returned after study.

Adaptation of the homonymous novel by Eduardo Gutiérrez, inspired by a real police chronicle, starring a gaucho killed by the police in 1874. Juan Moreira's life was full of injustices and has been considered representative of those suffered by gauchos.
