Doctor William Benson (Stelio Candelli) is driving to see a patient when he almost runs down a woman, who promptly disappears. While looking for the mysterious lady, he hears a crash. Investigating, he finds a beautiful woman (who we later learn is named Susan) unconscious in her car. The doc goes for help, happening upon a nearby castle, where he runs into several strangers, including a lady (who we later learn is named Evelyn) who is the exact likeness of Susan. Meanwhile, Susan arrives at the castle where she runs into Peter, who is the exact likeness of William. Much confusion follows (for the characters and the viewer). Susan and Evelyn (both played by Rita Calderoni) get naked a lot, as does a mysterious servant girl (Iolanda Mascitti) who pops up to indulge in lesbian sex and be flogged by a butler (Renato Lupi, whose blacked-out 'missing teeth' are not in the slightest bit convincing).
As its title suggests, Euro-horror Nude for Satan features lots of T&A, kicking off immediately with a pre-credits scene in which a naked woman runs in slow motion through a foggy wood. Once William has entered the castle, there's a steady stream of nudity, mostly courtesy of Calderoni, who has a splendid set of breasts and a wild '70s bush. Writer/director Luigi Batzella's trippy story and surreal visuals result in a film that is largely incomprehensible, and not even the copious amount of skin on show can prevent it from being a colossal snoozefest. A bizarre scene where Susan falls into a massive spider web and is terrorised by a pipe-cleaner arachnid is hilariously bad, but outstays its welcome, the spider inching slowly closer and closer to the screaming woman (who does well not to burst into fits of giggles).
For his final act, Batzella gets seriously arty, with lots of slow motion dancing from a couple of scrawny naked chicks and two blokes painted blue on one side. None of it makes a jot of sense. A copout 'It was all a dream, or was it?'-style ending wraps up this sorry mess.
