The Lady and the Cellist (1965)

On a bright summer's day in the early 20th century, a young man sits on a cliff by the sea to practice his cello. Unfortunately, the young man's ferocious playing style rouses up a storm which causes the waves to sweep a young woman (who was gathering shrimp by the shore) out to sea. The heroic cellist dives in to save the woman and finds himself battling some sea creatures for posession of both the woman and his cello.
