After the Fog (1930)

Millionaire Joshua Barker insists that his daughter Faith must marry Phil Langhorne, a man that neither likes, and Faith is in love with and eager to marry her childhood sweetheart, John Temple. Faith sets out to investigate what hold Langhorne might have on her father. The search takes her to an island during a fierce sea-storm on a dark and windy night; the sentinel light in the lighthouse suddenly goes out and the family yacht is about to crash upon the great rocks of the island.
