Long before time had a name, Ninjago was created by the First Spinjitzu Master by using the Four Elemental Weapons of Spinjitzu; weapons so powerful, no one can handle all of their power at once. When he passed away, his two sons swore to protect them, but the oldest, Lord Garmadon, was consumed by darkness and wanted to possess them all. A battle between brothers broke out and Lord Garmadon was struck down and banished to the Underworld. Peace returned to Ninjago as the younger brother, Sensei Wu, hid the elemental weapons in the far corners of Ninjago. Centuries later, Lord Garmadon has returned with the help of his Skeleton army to collect the Golden Weapons. Sensei Wu turns to the aid of four young Ninja who are to be trained to become the protectors of each of the weapons. Although the Ninja successfully survive a harrowing quest to retrieve the elemental weapons, they fall into Lord Garmadon's master plan, releasing the dark Lord from his prison, and allowing him to escape ...

With the ninja imprisoned, Nadakhan uses the Realm Crystal to free his old crew. The ninja encounter Captain Soto who tells them the story of how he originally trapped Nadakhan in the Teapot. The secret, he says, is the venom of a Tiger Widow, a rare creature that lives on only one island. The venom can slow a djinn down. Soto is the only one who knows where the island is and will only tell if the ninja break him out of jail. Meanwhile, Nadakhan has decided to return to his home realm of Djinjago, only to discover it is falling apart. The ninja's destruction of the Cursed Realm is affecting the realms connected to it. Nadakhan uses the Djinn Blade to smash the Teapot, absorbing all the spirits that were trapped there into the sword. Nadakhan vows revenge on the ninja and NINJAGO. The ninja and Soto escape from jail, only to find out the map to the island is on Nadakhan's ship. Nadakhan discovers that Nya looks just like Delara, his long-lost love.

The ninja's search for Nadakhan's ship turns up nothing. Nadakhan's crew is struggling to handle an airship which used to sail only on the oceans. Nadakhan confronts Jay and talks him into making a wish that will win him Nya. Jay wishes that he wasn't born in a junkyard and was rich. The next moment, he receives a letter saying his father has died and he has inherited his estate. Jay rushes home to find his parents in the junkyard and finds out they are fine, but they reveal that he is adopted. Jay discovers that his real father is the actor who played his favorite movie hero. In an effort to trap the ninja, the Sky Pirates start raids all over NINJAGO City. Nadakhan kidnaps Kai, who makes two wishes, both of which go wrong. His third wish is to make it all go away. Nadakhan's first mate, Flintlocke, accidentally destroys the Realm Crystal and Cole steals Soto's map. The Destiny's Bounty mysteriously vanishes from the police impound yard.

The ninja travel to Tiger Widow Island to get venom from a tiger widow spider to use against Nadakhan. The plan goes awry when Nadakhan and his sky pirates arrive to intervene.

Jay must do what it takes to escape the villainous clutches of Nadakhan whilst the remaining ninja attempt to survive and escape Tiger Widow Island.

The ninja are trying to save Jay from Nadakhan's ship. Two screenwriters, Kevin and Dan, suggest that they disguise themselves as Sky Pirates. The ninja infiltrate the ship and Cole goes to slip the venom into Nadakhan's drink. But he stumbles on Jay, helps him escape, and forgets to use the venom. The two of them, plus Nya and Lloyd, wind up captured by the pirates. For a while, it looks like the ninja might win out until Cole wishes they were all out of here - and the pirates' airship starts to tilt dangerously. Lloyd wishes to be wise like Sensei Wu and starts to age rapidly. Everyone falls off, but Nya wishes for the clouds to save them. They land on the now substantial cloud and the battle resumes. Nya and Jay fall off but combine their powers to create a hydro-electric dragon. Nadakhan captures Lloyd and Cole in his sword and orders Flintlocke to recapture Nya, but she and Jay escape.

Jay and Nya have been holed up at the police precinct, but the Sky Pirates track him down. They flee by boat to the lighthouse where Zane's father was once held captive. Nadakhan learns that the ninja still have the Tiger Widow venom. Flintlocke leads a mutiny against Nadakhan, convinced that the djinn will abandon his crew once he has the power of infinite wishes. Nadakhan defeats Flintlocke. Nya and Jay discover a hidden basement in the lighthouse. They discover Echo Zane, a rudimentary version of their friend made of copper and bits and pieces from the island. Nadakhan forces Clancee to use one of his wishes to discover where Nya is hiding. Jay and Nya rig up booby traps and defenses all over the island. The pirates attack in force. Jay and Nya fight bravely, but the tide turns against them. They briefly escape and Nya uses Traveler's Tea to get Jay to safety. Nya is captured by the pirates.

Jay lands back in the junkyard owned by his adoptive parents. Meanwhile, the pirates are getting Nya ready for her wedding rehearsal in the Djinn Temple. Dogshank discovers that Nya was concealing a blowpipe with a dart coated in Tiger Widow venom and orders Clancee to get rid of it. Jay recruits Dareth, Captain Soto, Skylar, Ronin, Echo Zane, and the Commissioner into a new team. Jay and the team hitch a ride on the next piece of land stolen by Nadakhan to get up to the djinn's ship. Jay gets his hands on the Djinn Blade and voluntarily goes into it in search of his friends. Jay succeeds in freeing the ninja, Sensei Wu, and Misako.

The restored ninja rush to save Nya, but they are too late: the wedding to Nadakhan happens. Nadakhan now has unlimited wishes and no rules governing them. Clancee betrays Nadakhan and tells the ninja where the dart with the venom is. Angered, Nadakhan banishes Clancee, Doubloon, and Monkey Wretch with a wish. Dogshank and Flintlocke team up with the ninja to battle magical duplicates of Nadakhan. Meanwhile, the djinn casts a spell to restore Delara's spirit in Nya's body. The ninja take over Misfortune's Keep and ram it into the Djinn Temple. During the battle, Flintlocke shoots Nadakhan with the dart, and the djinn's magic spells start to reverse themselves. But some of the poison gets on Nya, who is dying. Forced to use his last wish, Jay wishes that Nya had taken his hand long ago when he offered it ... and that no one had ever found the Teapot of Tyrahn. The ninja find themselves back in NINJAGO City at the start of this adventure, with Jay and Nya now a couple.
