The story is about a mad, bloodthirsty lady who murders countless young females for their pure virgin blood, in order to prevent aging. The Countess kills hundreds of girls, most of which are adolescents and children; we see about 6-7 of all the murders. Her castle's basements are filled with the rotting bodies of the people she killed; a man graphically speaks about it, telling another man that he wouldn't want to see this: "bodies of children in putrefaction, with eyes devoured by maggots" (we do not see any of it).
A little girl takes a chick and buries it alive (very disturbing). Afterwards we see the chick rotting away with maggots.
A man is decapitated with a sword and blood sprays out (brief but graphic).
A dead little girl is seen being ripped apart and eaten by wolves (rather graphic).
The Countess slices the throat of a girl (a lot of blood spills out).
Two women and one man are condemned to be killed: the man by decapitation, the women by strangulation (we do not see it).
A man and a woman engage in a sadomasochistic sexual practice, in which the woman whips the man (the latter is a masochist and visibly enjoys the torture).
The Countess cuts the skin above one of her breasts and inserts a lock of hair in it; she then proceeds to sew up the deep cut, closing it (the whole sequence is very graphic and bloody).
The Countess scratches her fingers on a wall and blood comes out of her fingertips; she then sucks on it.
