Mysterious goings on at a lighthouse off the Welsh coast.
Sam (Gordon Harker) turns up for his new job at an important lighthouse on the coast of Wales. He learns that one of his predecessors has been murdered, and another one has one mad after seeing a phantom light. With a growing number of people turning up at the lighthouse including Alice (Binnie Hale) and Jim (Ian Hunter) all of whom are not quite what they seem. A plot is uncovered to disable the lighthouse and cause a ship to be driven onto the rocks by a phantom light, for insurance purposes.
A fine film which has a number of layers and, despite a short runtime, the story is given time to build. The lighthouse setting gives the mystery a claustrophobic edge.
