KEOMA (1976) - Fine Spaghetti Western starring Franco Nero as a half breed who is the favorite son of four children. Keoma's mother was Native American while his half brothers were not. The story concerns a town that is faced with the plague and I'm guessing it was small pox, but they only call it the plague. Keoma saves a woman from quarintine at great expense as he eventually has to face all his half brothers in the final showdown. Good Italian Western and one of the last of the genre.

By the way the music in this film is unforgettable. It's still with me 3 days later. Unique and original musical score that I know that everyone will find interesting.
