Psychic researcher Tom Preston (Tom Skerritt) knew it was time for a final showdown with the Satan-worshipping cult that had stalked his family for generations in order to reclaim the arcane tome in the Prestons’ safekeeping. Can he succeed even though the Satanists’ leader (Ernest Borgnine) has Tom’s brother (William Shatner) in their thrall? Otherworldly shocker co-stars Ida Lupino, Eddie Albert, Keenan Wynn, and, in his film debut (albeit barely glimpsed under heavy make-up), John Travolta. 86 min.
