Edgar Allan Poe's Lighthouse Keeper (2016) on Netflix

Plot summary

A man regains consciousness on a beach, his forehead wounded, and sees a woman walking away. He collects his satchel and trails after her, but a fall while he climbs a cliff leaves him unconscious. He comes to inside a lighthouse without any memory of who he is. The keeper, Walsh, explains that they are stranded together on a remote peninsula with no route out, and that a ferry bound for San Francisco will not arrive for two weeks. Walsh adds that a light must stay lit all night. The next morning he goes into the woods, finds the woman again, and learns she is Nora. She tells him Walsh is insane and that she stays away from the lighthouse. That night, when he extinguishes the candle, he witnesses spectral creatures.
