One day Ninjago went to Phoenix Drop and meet Aphmau and her friends...but little did they know that the stone army and Zane have teamed up to take down Aphmau and her friends and Ninjago.
Kai thought that they were ready, that they had trained enough to fight against the Overlord and his army of Stone Warriors. But after losing Jay, Cole, Zane, Nya, and Lloyd to the Overlord, the fate of Ninjago fell onto his shoulders. Can Kai handle the pressure, or will all of Ninjago fall prey to the Overlord's clutches?
