I Was A Teenage Frankenstein's Roommate is the story of Hiram Belmore (Patrick Casey) and his attempt to create life and therefore win the school science fair. Peggy (Sarah K. Bizek) and her boyfriend Dwight (Nick Stukas) are house-sitting for Peggy's professor. Dwight's friend Hiram hijacks the house and uses it in his experiment to create his Frankenstein's monster, which he names Monster (Worm Miller). His class rival Lionel Kerr (Sean Hall) is trying to prevent this and win the science fair himself, while Clerval (Jack Shreck) co-opts control of a religious sect to make things turn out in his favor and wackiness ensues.
