The ninjas find themselves going from famous heroes to hunted villains when someone impersonates them and commits crimes all over Ninjago City.

While Nadakhan schemes to steal the Realm Crystal, the fugitive ninjas are pursued by Ronin, who has been hired by the police to track them down.

Falsely imprisoned, the ninjas meet a fellow captive who knows of a rare venom that can stop a Djinn like Nadakhan, but it's only found on one island.

As large areas of Ninjago City vanish, the ninjas head to Tiger Widow Island, where Jay collects the precious venom with Nadakhan in hot pursuit.

Marooned on Tiger Widow Island, Lloyd, Cole and Nya try to escape on a raft, while a captured Jay battles Nadakhan's crewmates for their amusement.

After lessons in how to talk like pirates, the ninjas infiltrate Nadakhan's ship on a mission to slip him the venom and rescue Jay from captivity.

Flintlocke leads a mutiny, believing Nadakhan will abandon his crew once he has the power of infinite wishes, but the Djinn prevails and captures Nya.

While Nya is forced to rehearse for her wedding to Nadakhan at the Djinn Temple, Jay recruits a new team for a mission to rescue his friends.

Nadakhan marries Nya and gains the power of infinite wishes, but Flintlocke and Dogshank join the ninjas to fight the Djinn in an epic final showdown.
