== Official Description ==
The ninja and fighters discover there's a strategic location called the Corridor of Elders where they can make their last stand against Chen's Anacondrai army...but even with the new Destiny Bounty, their forces still aren't strong enough. Fortunately, Pythor escapes Chen's clutches and discovers there is one spell in the Book of Magic that could stop the war, but at a serious cost.
== Synopsis ==
Master Chen's anacondrai army lands in Jamanakai Village as its citizens flee in terror. They then continue onward, as Chen declares they won't stop until every village is conquered. Meanwhile, the ninja and the other elemental masters are scattered all around Ninjago, after chasing down the decoy trucks. Nya attempts to contact them from the new Destiny's Bounty, but Chen takes over the airwaves and reveals to Misako that it was Wu who wrote the letter that caused her to fall in love with Garmadon. Angered, Wu declares that Garmadon is no sensei, though Skylor quickly breaks up the fight.
In Chen's camp, Pythor is still running from the rodent, though manages to escape and comes across the book of spells. Just then, Cyrus Borg delivers a message via the radio that more villages have been overrun. Elsewhere, Lloyd meets up with Neuro who informs the green ninja that Chen's army is heading west. Lloyd instructs the Master of the Mind to send a message to the other elemental masters ordering them to Nya's Samurai Cave, where she informs them that Chen has taken over the entire eastern coast. Wu points out that the Corridor of Elders will be the best place to make their final stand, and the elemental masters agree. The ninja journey all over Ninja to rally support from the citizens.
The Ninja, citizens and Serpentine get to the Corridor and start the ultimate battle against Anacondrai. Pythor escapes Chen's camp riding a rat and carrying Chen's spell book. He gets to the battle and tells Lloyd to take him to his father because he knows the way to end the battle. Lloyd carries him to the Destiny's Bounty where he tells Garmadon that he can sacrifice himself by going to the Cursed Realm and unleash the spirits of ancient Anacondrai warriors including Arcturus. Lloyd gets angry and flies away on a flyer. He remembers the past with his father while defeating Anacondrai. Wu begins to read the spell to open the portal to the Cursed Realm but Lloyd comes back and stops him, saying that he will do it instead of him. The portal opens, Garmadon enters it and unleashes spirits of Arcturus and his troops who quickly curse Chen and his soldiers turning them into ghosts. They all get hovered into the portal, which then explodes. The war ends, but Lloyd gets sad because of his father's banishment. Arcturus's spirit comes to Pythor and says that he is their ancestors' proud, and turns him into back to normal size. 
Later that day, the ninja, Wu, Misako, and Dareth sit around a fire on a broken statue, watching construction workers building statue of Garmadon in the corridor. Lloyd tells that today they will say goodbye to a legend and burns the book in the fire. In the end, Morro appears spinning in the air and screams "Morro!", indicating the spirits of the Anacondrai weren't the only ghosts that got released from the cursed realm.
