Just as the rebuilding effort in Ninjago begins, the four ninjas realize Lord Garmadon has forged the ninjas' lost Golden Weapons into a mega-weapon.

When Garmadon accidentally brings to life the ruthless Captain Soto and his pirates, it's up to the ninjas to stop them from plundering Ninjago City.

When our heroes are invited back to Darkly's Boarding School, they discover it's a trap set up by Lord Garmadon and his evil replica ninjas.

When the ninjas prevent Garmadon from using his mega-weapon to bring to life a fossilized monster, they're turned into kids and need Lloyd's help.

When Garmadon travels back in time to undo the past and rid the future of ninjas, the ninjas follow him and try to stop him using the Golden Weapons.

The ninjas face off with an exhibit of a stone samurai warrior that the toxic venom from the Great Devourer has brought to life.

The ninjas try to flee from the Stone Army, which has been brought to life by the Devourer's toxic venom. Garmadon tries to seize control of the army.

The ninjas, Lloyd, Sensei Wu and Misako journey to the Dark Island to find a Temple of Light that can restore the ninjas' elemental powers.

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.
