Here's what it is All About.
I actually heard about the movie on the Pat & Brian show on Beyond Investigation Magazine's site(www.beyondinvestigation.com), listening to their radio broadcast. It is loosely based on the Tate murders, inspired by the producer David Oman, who built his home just down the street from where the murders took place and has had strange things occur. The story is about that part of it, as I understand it.
They replay the interview with David on a daily basis which goes into greater detail..not sure of the schedule though.
