Workers in Patagonia, influenced by anarchist ideas, demand improvements in hotel pay and conditions. After employers initially agree to workers' demands, which are supported by workers in other sectors and areas, the regional governor, under pressure from local employers, order the paramilitary police to intervene to suppress union and political activity, despite the protests of a local judge. In response to such harassment, a general strike is declared, paralyzing the ports and wool production for export. The nationalRadical Civic Union government supports the workers' rights, and the workers call for union recognition and improvements to the conditions of agricultural workers. Employers reject the demands and bring inreplacement workers, but the convoys are attacked by armed strikers who shoot down the soldiers guarding them. Workers use arson and sabotage to disrupt production and take hostages. More fighting erupts between armed police and strikers. An army- and judge-led mediation attempt commissioned by President Yrigoyen condemns police partiality and the exploitative nature of the company store system. After six weeks, the strike is settled in the workers' favour with the first ever collective agreement for Patagonian rural workers and they hand in many of the weapons they seized from the rural estates. Employers are outraged by having the unfavourable terms imposed on them by the government and respond with selective sackings and denial of service at company stores. Workers respond with boycotts and the president dismisses the governor. More importantly, landowners refuse to implement the pay rise specified in the agreement. With workers planning another strike to enforce the terms of the agreement, employers, backed by Chile and Britain, successfully force the government to round up union leaders and militants. Another general strike is called in response. While strikers take hostages to defend themselves, bandits take advantage of the unsettled situation to raid isolated estates. The army is ordered to restore order in such a way as to permanently remove the threat of rebellion due to socialist or anarchist ideas, which they do by using acting in force, opening fire on strikers without warning and carrying out summary executions, especially of the leaders and even of delegations acting under a flag of truce, some of whom are made to dig their own graves. Others are tied naked to fences or made to run the gauntlet. The strikers, to whom the army had previously acted sympathetically, are caught by surprise. Armed landowners participate in the suppression of the strikers, identifying the leaders. After the slaughter, the previous agreement is annulled and wages are reduced. The film ends with oligarchs congratulating the lieutenant colonel in charge of the massacre during a celebration and singing For He's a Jolly Good Fellow in English.
