Real horror that I saw as kid in late 80’s or early 90’s. It’s about a girl that has been kidnapped by some cult and she is possessed. At the end of the film cult members caught her mother and took her in some cave or underground or some abandoned place and tied her to altar for sacrifice that her daughter needs to do. So the best scene I remember is that the girl is holding a sacrificial dagger and her eyes shine like gold and silver, like a shinny coins instead of eyes. Very striking scene. It’s not classic The Wicker Man nor Village of the Damned. Film that I find very hard to find, unfortunately.
