American Guinea Pig: Bloodshock

A couple of young women are abducted and become the unwilling stars of a snuff film, wherein they are brutally tortured.

A young man suffering from significant childhood trauma believes there are portals to the darkness around him that can be accessed through extreme self-mutilation. He locks himself in his home and proceeds to perform acts to summon the Goddess Ishtar to help him cross over to the other side.

A young woman, after driving her father to suicide, is examined by the Catholic Church, who determine that the girl is in fact possessed, and a wave of priests wade in and out of the demonic gore.
