A lonely and neglected housewife (Lana Wood) living in a deserted house on the beach takes a lover. Unfortunately, that lover turns out to be Satan! Her husband and teenage daughter are naturally upset by this turn of events and enlist a family friend (Britt Ekland) who is a spiritual medium and the latter's obnoxious husband to help them out, with disastrous results for everyone involved.
This movie kind of resembles both the mainstream film "The Entity" and the X-rated classic "Through the Looking Glass", but it is not as good as either. It is surprisingly low-budget and obscure movie considering that it features two former Bond girls--Lana "Plenty O'Toole" Wood and Britt "Holly Goodnight" Ekland. (okay, not two of the most talented former Bond girls, but still--). A cadaverous John Carradine also makes an appearance (but then he showed up pretty much every time he sensed the distant whir of a film camera). Ekland, very uncharacteristically, keeps her clothes on for the whole movie, but the busty Woods more than makes up for this as she repeatedly scromps naked with the horny demon, moaning ecstatically. The film is not bad, at least before the completely confounding ending, but there are few too many supposedly meaningful shots of the waves crashing onto the beach.
Not a good film perhaps, but not deserving of its current obscurity either.
