Blood Mania (1970) 
Light on the blood, heavy on the mania, Blood Mania tells the story of nymphomaniac Victoria who hatches a plan to kill her bed-ridden father to gain her inheritance in order to help his adulterous doctor pay a debt he owes to a blackmailer. However, not all goes to plan.
Dirty double-dealings, sexual shenanigans and psychosis help to enhance an otherwise tired and bland storyline full of melodrama and tepid performances. The final scenes are quite fun where the mania reaches its peak and we actually finally get to see some blood as the title promised.
