Sensei Wu has sent Cole, Jay, Kai, and Zane on their first mission. The four Ninjago warriors must recover the Scythe of Quakes, one of the Four Golden Weapons, before they can go head-to-head with Lord Garmadon. But Kai has his own ideas about how to recover the Weapon. Can Cole, Jay, and Zane convince him they're all playing for the same team?
