Roy Boyd

A woman becomes very curious about one of her psychiatrist husband's inmates, a man who was found guilty in the murder and disfigurement of his former wife.

When a young girl mysteriously disappears, police sergeant Howie travels to a remote Scottish island to investigate. But this pastoral community, led by the strange Lord Summerisle, is not at all what it seems.

Edward Woodward stars as Sergeant Howie, a naive young police officer sent to Summerisle, a secluded island off the coast of Scotland, to investigate the disappearance of a young girl named Rowan. When he arrives there, he finds a very tight-knit community that is mistrustful and hostile to outsiders. Soon, Howie begins to realize that the town might be a strange pagan cult, one given to unbridled sexuality and possible human sacrifice. Seeking an audience with the oddly civilized Lord Summerisle (Christopher Lee), Howie hopes to get to the bottom of the mystery, but instead he finds something more shocking than he could have ever imagined.
