1940s Germany: Marie, a death camp escapee on the run from the Nazis, swims towards Westrode Island, where a lighthouse is manned by a half-mad keeper, Wolfe Kristan. Brought aboard the lighthouse she begins to fall in love with the assistant keeper who, unknown to her, is a British spy. As the couple become more intimate, Kristan s jealously finally pushes him over the brink and into full-blown madness...

Featuring a career-best performance from Wilfrid Lawson as the deranged lighthouse keeper alongside Hollywood stalwart Michael Rennie and Mexican-American actress Movita Castaneda, this intriguing, genre-defying wartime thriller is presented here in a brand-new transfer from the original film elements, in its as-exhibited theatrical aspect ratio.
