This classic of the Latin American cinema is based on actual historical events involving the brutal military suppression of a series of strikes during the early Twenties by rural workers in the southernmost province of Argentina. The film’s narrative, set within a richly detailed social context and mounted as a colorful action film, features fascinating character studies of the main protagonists, including the anarcho-synicalist leaders of the workers’ movement and the military commander who realizes too late that he is merely a tool of the wealthy landowners.
