After fighting off the Stone Army, the ninjas arrive at the Temple of Light and harness their pure elemental powers, concentrating them onto Lloyd.

The ninjas try to return Garmadon's Helmet of Darkness to its perch at the Celestial Clock to prevent the final battle between Lloyd and his father.

Garmadon uses his new super-weapon to turn Jamanakai Village evil, unsettling the balance and allowing the spirit of the Overlord to possess his body.

A great darkness has fallen upon Ninjago as Garmadon's super-weapon has turned it evil, but the ninjas discover light is more powerful than dark.
