Two Mules for Sister Sara

A hard-hitting high plains drifter (Clint Eastwood) rides into town and single-handedly rescues a local nun (Shirley MacLaine) from a gang of attackers. After meeting a band of Mexican revolutionaries bent on resisting the French occupation of Mexico, the cowboy and Sister Sara decide to join forces with the freedom fighters and set off on a deadly mission to capture the enemy's garrison. But along the way, a steamy romance develops between them when the soft-spoken hero discovers the nun is not what she seems.
