Green Dolphin Street (1947) - It Must Be St. Peter

Donna Reed as 1840-something Channel Islander Marguerite is distraught over the (Spoiler!) consecutive deaths of her parents, wakened by the waves at the foot of the cliff-side convent, chooses to approach (though it’s not strictly necessary) through the old smuggler’s cave, thus a dramatic sequence for the MGM special effects team, in Green Dolphin Street, 1947.
