A Roman Catholic nun and a hard-bitten US Marine are stranded together on a Japanese-occupied island in the South Pacific during World War II. Under constant threat of discovery by a ruthless enemy, they hide in a cave and forage for food together. Their forced companionship and the struggle for survival forge a powerful emotional bond between them.
Unfortunately the movie Heaven Knows, Mr. Allison is not yet available on HBO Max.
