Content warning: animal death (rattlesnake)
Sister Mary Joseph (Leslie Caron) is the only survivor of a wagon train massacred by Apache on the way to a mission in Santa Fe. She wanders haplessly through the desert until she meets Madron (Richard Boone), a gunslinger on the run after a bad business deal. Madron has managed to piss off an Apache named Sam Red (Chaim Banai) and now Sam and Madron's former business partners are all after him. Still, he's not the kind of man who would let a nun travel by herself, even if he can't really understand what a nun is.
It's the Volcano vs Dante's Peak of Westerns-featuring-men-exasperated-by-hot-nuns, coming out the same year as Two Mules for Sister Sara. It's not nearly as memorable, however. It looks like a made-for-TV movie but was inexplicably nominated for an Oscar for Best Original Song, a thoroughly sappy piece of work called "Til Love Touches Your Life."
It's always nice to see Caron, although she is acting circles around Boone. Strictly for die-hard Spaghetti Western fans, I think, but it's streaming on Amazon Prime.
