You've never seen the Mystery Inc. gang like this before as Fred, Velma, Daphne, Shaggy and Scooby-Doo seek answers to the mystery plague that turned the world into a monster strewn wasteland. But now something strange has happened to the marauding monsters - they're suddenly all single-mindedly heading in one direction, almost like they're under a spell. The gang are tracking the parade of monsters to find out - much to Shaggy's chagrin. But, Scrappy-Doo and his vicious pack of Smart-Dogs are hot on the trail too and they're determined to follow it straight to Velman. Will the Mystery Gang Inc. survive?
