Blue Falcon and Dog Wonder encounter The Worm, an evil genius abetted by escaped convicts Bugsy Busby and helicopter thief Roto Chopper, seeking revenge against Big City. Swooping down on Big City Tech (scene of a freak accident years back when The Night Crawler, then Professor Ronald Hickman, was transmogrified from an intelligent scientist into a worm), The Blue Falcon and Dynomutt discover and try to stop the villains' attempt to pilfer a multimillion dollar computer. Despite a string of Dyno DumDums, The Daring Duo lure The Creepy Crawler and his even creepier cronies into a bizarre underground pursuit (where else would worms go?) and trick them into burrowing into Big City Prison.
