Sensei Wu has gathered a powerful team of ninja warriors. Now he must train them in the ancient art of Spinjitzu. If he fails, Lord Garmadon and his evil skeleton warriors will destroy the land of Ninjago and all of its inhabitants.
Each ninja's training has its own challenges. And Zane, the most mysterious of the ninja, might have the most difficult time of them all. While a dedicated member of the team and an avid learner, Zane has no memories of his past, but a powerful desire to recover them. Could it spell disaster for the whole team?
