Cult horror classic in which devout Christian policeman Sergeant Howie (Edward Woodward) finds himself summoned to a remote Scottish island to investigate the disappearance of a child. On arrival, Howie finds himself increasingly isolated and humiliated by the actions of the island's community, who belong to a bizarre pagan cult led by the charming Lord Summerisle (Christopher Lee). As preparations for a sinister ritual celebration reach fever pitch, Howie, whilst trying to fend off the advances of the local landlord's daughter Willow (Britt Ekland), begins to suspect what role the islanders intend him to play.
