Macho Callahan (1970)

During the American Civil War, Confederate soldier Macho Callahan finds himself behind bars at Camp Hawks. He manages to escape from prison and tries to find and get revenge on the person responsible for his imprisonment. However, a gang of "bounty hunters" is on his trail. By an unfortunate coincidence, Callahan kills a completely different person along the way, and the vengeful widow is already watching Macho.
