Vicky loves Ricardo but Ricardo loves Barbara. So, Vicky goes to a gypsy witch who convinces her she must make a pact with Satan in order to cast an effective love spell on Ricardo. After Vicky gives her body and soul to the Dark One, she engages with Ricardo in a passionate night of lovemaking that is cut short by Satan, who, sensing that Ricardo has not completely fallen under the spell, orders Vicky to kill him. Following Ricardo's death, his brother Carlos is haunted by nightmares of the dead sibling, who appears and takes possession of Carlos in order to get his revenge on Vicky. This 1984 release uses mucho footage from the 1968 film Cautivo del mas allá, but adds new scenes of gore, zombies and nudity.
