From the liner notes

In a genre defined by shocking violence and psychosexual kink, it remains perhaps the most over-the-top giallo in EuroCult history: Former MGM starlet and doomed James Dean paramour Pier Angeli – two decades past her Golden Globe award for ‘Most Promising Newcomer’ and just one year before her tragic death – stars in this ultra-lurid epic packed with decapitations, pet vultures, creepy incest, groovy fashions, cyanide baths, swirly psychedelics, inexplicable plot twists, Nazi death camp flashbacks and more. Eleonora Rossi Drago (Camille 2000), Fernando Sancho (Return Of The Blind Dead) and Luciano Catenacci (Kill, Baby Kill!) co-star in the 1970 sickie that would make Freud himself scream in horror, now fully restored from the original Italian vault elements.
