The Wicker Man

Off the coast of Scotland, the natives of a small island owned and run by a Lord Summerisle, immerse themselves in a religion based on pagan rites and rituals, totally antithetical to Catholic dogma. When a devout Christian police sergeant from the mainland comes to the island to investigate the mysterious disappearance of a local 12-year-old girl, he stirs up hatred and resentment among the locals to such an extent that for their annual May Day celebrations, to insure the crops don't fail for a second year in a row, he becomes their target to appease the heathen goddess of the harvest.
