The Devil in Baby Joan Teaser Trailer has premiered. Michael Metzner‘s The Devil in Baby Joan plot synopsis: based on true events, the film deals with a seemingly ordinary man of God and demonic possession in Australia. Things are not always what they appear to be though. The “Oh, the blood of Jesus” song at the beginning of the teaser trailer is a good indicator. By the end of this teaser trailer the viewer sees what is really going on and the true nature of the man of God. Twisted. Could be good.
