Blood On Satan's Claw (Tigon British Film Productions - 1971)

After a plowboy accidentally unearths the skeletal remains of a demonic creature, a cult of teenage devil-worshippers emerges in a 17th-century Cornwall farming community, led by the gorgeous temptress Angel. Together, the children begin performing blood sacrifices in order to bring the skeletal demon back to life. The film eventually steers into witch-hunt territory -- in the vein of Michael Reeves' Witchfinder General -- as the superstitious locals use inquisition-style practices to put a stop to Hayden's cult.
