When a wandering mercenary named Hogan rescues a nun called Sister Sara from the unwanted attentions of a band of rogues on the Mexican plains, he has no idea what he has let himself in for. Their chance encounter results in the blowing up of a train and a French garrison, as well as igniting a spark between them that survives a shocking discovery.
Two Mules for Sister Sara is a 1970 American-Mexican Western film in Panavision directed by Don Siegel and starring Shirley MacLaine and Clint Eastwood set during the French intervention in Mexico (1861–1867). The film was to have been the first in a five-year exclusive association between Universal Pictures and Sanen Productions of Mexico. It was the second of five collaborations between Siegel and Eastwood, following Coogan's Bluff (1968). The collaboration continued with The Beguiled and Dirty Harry and finally Escape from Alcatraz (1979).
