Poor Daniela. She was raped by a brute at age 13 and her family has a history of lycanthropy. Nevermind that she looks just like her great great aunt, furthering her delusions she's a bonafide werewolf. She's been having nightmares where she wolfs out and kills pilgrims, after dancing naked in a ring of fire (a very fine opening scene).
Daniela's wealthy daddy is concerned, moves her out to his Italian country home, and enlists the help of a doctor to figure out what the hell can cure Daniela from her mind. The doctor spends most of his time musing upon the obvious, such as, Daniela has sexual phobias because of her rape. Oh, really, doc? Why ever would you suspect that? And, Daniela is obsessed with antiques and old documents because she spends most of her time in the attic. Okay. Sure. Whatever you say. ..
