Meet Dude Harris - one minute surfing the crowd, the next, a real dead rock star! Luckily, with the help of some new ghostly pals, Dude discovers that the afterlife can be cool once you've grasped the rules. Ghosts aren't sad, scary spookmeisters - far from it, they're hip, happy and having a blast! But, where there's a ghost, there's always a ghostbuster. Enter Sid Wiper, computer nerd and slimeball, whose mission is to wipe out the ghost community. And he's found a way to do it. Dude and his mates set out to stop him - but is it too late?
