Ingrid Pitt

Both a bonafide horror classic (of the creepy, not gory kind) and '70s cinematic oddity, this British mystery from the pen of Anthony Shaffer (Frenzy) follows stuffy British Sgt. Howie as he travels to Scottish island Summerisle to investigate the disappearance of a young girl. While encountering a wall of silence amongst the town's odd inhabitants - including the beautiful, sexually liberated daughter of the innkeeper - Howie discovers a society steeped in secrets and strange, pagan rituals.
