The stranded ninja were the four original ninja (Kai, Cole, Zane, and Jay) and the de-aged Wu after they were stranded in the Realm of Oni and Dragons. They resolved to free the dragons from the tyranny of the Dragon Hunters, and return home to Ninjago. After Wu aged further and grew a mustache and a goatee, he proved himself worthy to the Firstbourne, and reclaimed his father's Dragon Armor. The newly titled Dragon Master Wu and the ninja boarded their respective dragons, and were finally able to return to Ninjago.
They were knocked out but awoke soon after to find themselves in the Realm of Oni and Dragons without any way back home.
While Cole and Wu go to scavenge for food, the others are captured by the Dragon Hunters. Cole and Wu then return to the base and realize the ninja are not there. Jay, Kai, and Zane are brought into Dead's End blindfolded by the Hunters. The captive trio are taken into a lair and their blindfolds are removed for them to meet Iron Baron, who mocks their predicament before he and the Hunters laugh.
When Iron Baron mistook the ninja as Oni, they are forced to face Slab. They were able to restrain him but Zane had to use his Ice to save Jay from Slab's Earth. Iron Baron then realized that they are actually Elemental Masters instead of Oni and told the Dragon Hunters to apprehend them.
Kai, Jay, and Zane are apprehended and were told the Hunters would be hunting for Dragons.
When they refused to help him, Iron Baron set off a device which created an Elemental reaction. After the Hunters caught the Wind Dragon, Cole tells them they will eventually find out how to solve all their problems.
The ninja planned to build Firstbourne as a distraction to escape. When they were encountered by the real Firstbourne, the Hunters prepared to hunt for the ninja.
The ninja woke up and noted Wu had aged overnight. Wu told them he had a dream about his childhood in which he was fishing with his brother and father. Heavy Metal approached them and asked if it's true he's the son of the First Spinjitzu Master. When Wu confirmed this, Heavy Metal revealed she's actually a woman named Faith. She asked if Wu knows where the Dragon Armor is, and Wu pointed in a direction. She then got a vehicle to carry their supplies and told them Iron Baron can't know she's helping them.
The Dragon Hunters pursued the ninja into the canyons but were defeated. The ninja, however, were unaware Jet Jack put a tracking device on their vehicle.
The ninja reached Oni territory and went in to look for the armor. They saw the land was abandoned but noticed the gates revealed a map to the Dragon Armor, which was located in Firstbourne's nest.
When the ninja woke up, Faith handed them chain guns and they started training by chaining up a rock. When they, and Wu, succeeded, they had Wu make an attempt to ride Stormbringer.
When they stopped to look at the map, they realized the Hunters were following them. They were able to defeat them, but Faith was captured in the process.
The ninja uncovered Faith under the sand but were surrounded by Dragon Hunters. They were tied up, but Wu escaped. He agreed to lead Iron Baron to the Firstbourne's nest while everyone else stayed behind.
The ninja began to rock back and forth to escape their ties. Jet Jack releases them and tells them they should go after Wu and Iron Baron. However, their journey ends when they see a bridge has been destroyed.
When they were reunited with Wu and Firstbourne, they traveled back to Ninjago.
