Os Mucker (1979)

In 1873 in Rio Grande do Sul, a group of peasants come together to form a community of brothers, arousing the enmity of the rest of the population. They are immigrants from the German region and develop a communitary social model, having the Bible as a code of morals, faith and conduct. The group's economic independence ends up irritating the locals to the point of provoking successive aggressions that culminate in a bloody massacre.

Unfortunately the movie Os Mucker is not yet available on HBO Max.
