A spaghetti western in which three adventurers team up during the Mexican Revolution. Mary O'Donnell, a radical Irish journalist, wants to foment a peasant revolt in Mexico. She enlists the help of a seedy bandit, Lozoya, by saving him from a death sentence in Utah. They meet a man calling himself Prince Dmitri Vassilovich Orlowsky, who claims to be a Russian prince, not to mention a man of the cloth. Wallach pretends to be a Mexican folk hero. The trio crosses the border, the two men seeking a cache of gold while O'Donnell pursues her revolution.
When his life is saved in a shootout by a fellow gunman whose life he in turn had saved, Alex Longmire promises to give up his way of life. Riding into town he finds the only job available is deputy to sheriff Jade Murphy, an honest man caught between small farmers and a local cattle baron. And he has a pretty daughter. So Longmire decides to stay and see if he can use his expertise with firearms for good.
