Director Anthony Balch, known both as a collaborator on film projects with William S. Burroughs and as a shrewd cinema programmer and distributor, made this cheesy but imaginative and good-natured horror show on a shoestring. Swinging singles Jason (Robin Askwith) and Judy (Phoebe Shaw, credited as Vanessa Shaw) take a holiday at an old, vaguely threatening English manor. By the time they figure out that the other houseguests have been lobotomized, it's too late.
