Bart meets a reclusive B-movie director, whose collection of horror, science fiction, and Radioactive Man is the envy of every hobbyist in Springfield. When the director announces a contest to give away his massive collection, every geek, nerd, and dweeb in town will do anything to win. Then, Homer pits himself against an exasperating and pesky pest — and this time it's not Bart! And, witness the reign of terror of Springfield's super villain Doctor Colossus! Finally, a school field trip goes awry when Bart, Milhouse, and Martin end up on a runaway train.
