Hi there.
Quite a few years ago I watched a movie that I just can’t recall the name of. Nor can I recall the actors. The movie begins centuries ago, there’s an old woman (I think she’s some sort of witch) with her 2 grown up children - a man and woman (Tra, I believe she is called). The movie then forwards in time to modern 1980’s where the man is seducing and killing young women to stay youthful, while his sister, Tra, wonders around old and haggard with long white hair. That’s all the info I have to go on. I’m wondering if anyone shed some light. Sorry it’s a little vague.
