 A new student arrives at South Park Elementary when his father comes into town on business. In this case, however, Dad is the Dark Lord Satan himself and the child is his son, Damien. Satan is in town to challenge Jesus to a one-on-one showdown of good versus evil on Pay-Per-View. While his father trains for the match, Damien has a hard time fitting in at school. All seems hopeless for him until he gets some helpful advice on making friends from Pip.
