The city of Metru Nui is divided into six parts. Each part has a guardian—a Toa—who watches over the Matoran who live there. However, something strange is happening: Matoran are vanishing and it's up to the Toa to find them and to discover what is causing the disappearances. Do the Toa have the skills to solve this mystery? Or will they finally meet their match?

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 Toa Metru are nearly powerless after their defeat of the Morbuzakh but they cannot rest. Instead they must venture underground to save the city of Metru Nui's Archives. The Archives contain the history of the city, the Matoran and even the Toa. However, a flood has allowed all kinds of creatures that are normally trapped there to escape and now the Toa must battle them to survive.
