A beautiful young woman named Christina arrives in Europe to visit her estranged relatives in a small castle for the reading of her dead father's will.

Christina winds up becoming one of the living dead herself, and at the end of the film, she and the rest of the family all solemnly march off into a swamp on the estate's grounds, accompanied by the Queen of the Night.

The following cast went uncredited:[1] The film was shot between November and December 1971 in Portugal, including around Palácio dos Condes de Castro Guimarães in Cascais and the nearby town of Sintra.

[1] The film is credited to a single production company, described by Franco biographer Stephen Thrower as the “notoriously untraceable” Prodif Ets.

The other version was called Christina princesse de l'érotisme which added a sequence of an orgy scene with actors not seen in the original 1971 footage.

Richard Whittaker of The Austin Chronicle called it “one of the most infamously mutilated underground favorites”, and said the original Franco version is the best cut of the film.

[13] Bill Gibron of DVD Talk rated it 3.5 out of 5 stars, calling it “a truly unnerving experience representing Franco at his most visually arresting”.

[14] Writing in The Zombie Movie Encyclopedia, academic Peter Dendle called it “an atrophied psychological horror, which is over-stylish and impressionistic to the point of incoherence”.
