After getting married with her husband (Simón Andreu), Susan (Maribel Martín) travels with him to his isolated manor. The sexual drive of the husband is intense, and Susan feels repulse for his sexual games and perversions.
Susan notes that there are only paintings of his male ancestors and none of their wives and she learns that the pictures are kept in the basement. When she sees the painting of Mircalla Karstein (Alexranda Bastedo) without her face, her husband tells that Mircalla killed her husband in the honeymoon. During the night, Susan has dreadful nightmares with Mircalla.
When Susan's husband finds a naked woman buried on the beach, he brings her home and finds that her name is Carmilla. Susan is seduced by the woman and they have a lesbian relationship. Meanwhile her husband realizes that his life is in danger and Carmilla is a vampire.
"La Novia Ensangrentada", a.k.a. "The Blood Spattered Bride", is an erotic and gore vampire film with an ambiguous story developed in a nightmarish atmosphere, but having a weak conclusion and lack of chemistry between Simón Andreu and Maribel Martín.
It is not totally clear that Mircalla Karstein is a vampire indeed and based on the news in the disappointing conclusion, the plot may be understood differently, with the disturbed and dysfunctional Susan meeting the deranged stranger and having sexual attraction and making lesbian love with her. My vote is six.
Title (Brazil): "A Noiva Ensanguentada" ("The Bloody Bride")
