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 (Linda Hayden, who positively smolders). 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. This lush, moody horror piece is superbly written, though the plot becomes a bit dense at times; the film was originally intended as a three-part series, but was eventually edited down to one feature. Still, Piers Haggard's assured direction keeps the threads together and provides just enough shock value to keep viewers on their toes. Watch for Peter Ustinov's daughter Tamara as one of the children. The Blood on Satan's Claw was also released as Satan's Claw and Satan's Skin.
