American schoolboy Matt Hatter arrives at the Coronet Theatre in London to find that his grandfather is missing. Then he discovers a cache of amazing gadgets and weapons which is housed in an ancient book called the Interactive Chronicles of Action and Adventure. The book proves to be a gateway to another dimension called the Multiverse.

Matt, Roxie and Gomez race against time to prevent man-machine Scorpiotron from draining the oases in the Sea of Sands and depriving the citizens of their precious water supply.

Gomez is shanghaied by Ghost Pirate Redbeard with the mistaken belief that he can help locate the lost Skull of the Black Raven, which will grant Redbeard the power to control minds. Matt and Roxie come to the rescue.

Tenoroc unleashes the Mummy, with orders to find the Eye of Ra and burn the Sea of Sands to a cinder. Only Matt, Roxie, Gomez and a camel stand between him and catastrophe.

The race to end all races is on - and the prize is gravity itself. It's Matt, Roxie and Gomez versus the revved up speed demon known as Cyber Racer and his mean machine the Dune Basher.

Lord Tenoroc dispatches dino-hunter Doc Fossil to unearth the demon beast, Terrorsaurus Rex. Matt, Roxie and Gomez must stop him - but first they have to face an army of hungry Eoraptors.
