In faraway Ninjago City, the forces of good and evil ... are related?!
Teenager Lloyd Garmadon has spent his whole life in the shadow of his evil warlord father, Lord Garmadon. But Lloyd had never let his dad's bad reputation stop him from doing the right thing. He and his friends Nya, Jay, Kai, Cole, and Zane are part of the Secret Ninja Force. Together, they use supercool mechs to fight Garmadon and his army of sinister Sharkmen. All that changes when Garmadon launches an all-out attack on Ninjago City. Now Lloyd and the Secre Ninja Force need to take the battle with Garmadon to the next level. Can they find the inner piece — er, peace — they'll need to save the city ... and themselves?
