This is a Christian documentary on the occult. This episode deals with a man named Curtis Kelley who came from a family history of "Voodoo".
Note: Nothing this man claims is similar to the Voodou religion. Some of it appears to be hoodoo/rootwork/conjure but twisted into evil witchcraft. I have never heard of any spirit named "Big Face" in Voodou that tries to trick you into selling your soul. That is not a part of the Voodou faith.
