'Roadkill: The Last Days of John Martin' centers on a cannibal who likes to pick up and kill stranded couples on the road, chop them up, and have them for dinner. His housekeeping also leaves something to be desired (human remains everywhere!). 'My Sweet Satan' is based on a true story in which a group of heavy metal fans in Ohio dabble in hallucinogenic drugs and Satanism, which culminates in a brutal murder.
