(From the publisher):
The Toa are searching for the Disks of Power. Without these Disks, they may never be able to defeat the Morbuzak that is destroying the city of Metru Nui. The Matoran say they will help, but at least one of them has his own plans. Will the Toa succeed in their quest? Or will someone that they thought they could trust betray them?
