Five of the most powerful people in the world gather at a mansion to inherit a blood legacy and a sixth person named Maggie Walsh is also on hand, although she, at first, doesn't understand why she is there in the first place.
There are some very good and shocking scenes including a swimming pool turning to glass with a beautiful woman swimming in it. The woman is played by Hildegard Neil. Veteran character actor Charles Gray is Karl, and his death is the most grisly of all. Roger Daltry is on hand as a rock star who also dies.
The star of the show is the very beautiful Katherine Ross as Maggie. I have always considered Ross an under appreciated actress. Also I have always thought of her as one of the most beautiful women during the 70's who appeared in movies. her role is very good and she handles the role very well as the woman who is reluctant to accept her new "gift".
Sam Elliot is her long suffering boyfriend, Pete Danner. He goes thru a lot of hell for Maggie, and in the end both understand what is happening.
This is a superior shocker in my opinion with a screenplay written by Hammer vet Jimmy Sangster. This Blu-ray is very Highly Recommended!!
