This cut-rate release from the English studio Tigon, best known as a producer of second-tier horror (the terrific Witchfinder General and Blood on Satan’s Claw) and sexploitation (Au Pair Girls, which is actually a bit of fun, and the SF-themed Zeta One), has the makings of an enjoyable countryside romp through ritualism and witchcraft, but it suffers from a split personality. Half of the film plays as a surprisingly straightforward nudie picture, with sisters Christine and Betty (Ann and Vicki Michelle, respectively) appearing reliably in various states of partial and utter dishabille. And the other half plays as a somewhat ambitious psychological horror movie about young Christine, the title character, who first submits to and finally dominates a coven of witches holed up in the woods outside London.
