Billy is very bored and restless.

His aunt Beryl tries to help him by bringing him a gift – an old magic trick that she found in the attic – The Can of Worms!

Billy opens the can – and chaos ensues as a gang of extraordinary worms run riot!

Unfortunately, an evil old Magician finds out and steals the magic worms in order to cause as much damage as possible.

Billy knows that he must get them – or the carnage and mayhem will return – for ever!
