Um Homem Dificil de Matar (1970)

Monte Walsh is an aging cowboy facing the ending days of the Wild West era. As barbed wire and railways steadily eliminate the need for the cowboy, Monte and his friends are left with fewer and fewer options. New work opportunities are available to them, but the freedom of the open prarie is what they long for. Eventually, they all must say goodbye to the lives they knew, and try to make a new start.
