An old movie I saw on TV when I was a kid. All I remember is they bring a woman to see many girls tied down to individual tables. The head master starts walking up and down the aisle of the tables to choose which girl's throat will be cut. The girl they finally choose is somehow related to the woman who is watching (maybe her daughter). The woman is horrified to find that they are going to sacrifice her daughter. They cut the girl's throat with a knife and collect the blood in a cup. They then want the woman to drink the cup of blood but she refuses, so they punish her by locking her up in a cave. In the cave these old women (look like witches) with long nails surround her and start scratching her. The woman screams, and is let out of the cave. There are scratch marks on her back.

Jebus, and I got spooked watching Preditor when I was five. You're movie is messed up.
