Long considered a mockery with his fellow professors Cordell (Robert Z’Dar) & Donnely (Dustin Diamond), professor Vern Drake (Joe Estevez) becomes obsessed with finding the Demonicron, a book said to open the gates of hell. Pushed over the edge after being fired by the dean (Lark Voorhies), professor Vern Drake begins his obsessive search for the Demonicron. Sure enough he finds the Demonicron and decides to conjure the demons found within the pages of the book to do his bidding and to get revenge on those who ridiculed him. However, when he only manages to translate half the words required to summon them, he only gets half size demons. Now the demons are anxious to prove that though they are half the size, they are double the trouble!
