The Left Hand of God (1955)

A man in priestly robes, seemingly the long-awaited Father O’Shea, arrives at a little-frequented Catholic mission in 1947 China. Though the man seems curiously uncomfortable with his priestly duties, his tough tactics prove very successful in the Seven Villages, as around them China disintegrates in civil war and revolution. But he has a secret, and his friendship with mission nurse Anne (an attractive war widow) seems to be taking on an unpriestly tone.
