Popular actors Tomaru and Ashina receive death threats from an unknown person, so Team 10 is assigned to a joint mission with Team 7 to guard them. The two teams assemble to get the details of their mission, but Boruto sees a beautiful girl he doesn't remember seeing before…

The movie studio where Team 7 and Team 10 have been assigned to is attacked by a mysterious ninja. The lead actress is wounded and Tomaru, the lead actor, picks Cho-Cho to be the stand-in! Tomaru's flirting has Cho-Cho on Cloud 9, but Sarada and the others worry that the lovestruck Cho-Cho has lost her focus on the mission!

The ninja in the gas mask appears again during filming and kidnaps Tomaru. Despite everything that happened, Cho-Cho continues to worry about Tomaru and berates Konohamaru and Moeri for failing to stop the abductor. Meanwhile, Ashina agrees to deliver the money as instructed in the ransom note.

Metal's father, Rock Lee, announces that he will train Metal to master the ultimate taijutsu technique, the Eight Inner Gates. The thought that he cannot fail this training fills Metal with anxiety, and he ends up buying an item that's supposed to calm his nerves. But it doesn't work, and his father ends up postponing the training. He then runs into Might Guy, his father's mentor and a hero of the Fourth Great Ninja War.

The first Five Kage Summit since the attack by the Otsutsuki Clan is held in Hidden Leaf. The current Kage as well as their predecessors assemble, except the Third Tsuchikage, Ohnoki. Boruto and Team 7 have been assigned security duty, but Boruto gets bored and lets his guard down. Then by chance, they encounter Ohnoki.

The ninja assigned to the Hidden Leaf Gate are attacked, and Mitsuki disappears. Boruto and Sarada are unaware of this when their scheduled mission is suddenly canceled. Worried, the two start searching for their teammate. When they learn that all the jonin have been summoned by the Hokage, they set out to find out what's going on.

Boruto and Sarada sneak out of the village and head to Orochimaru's research lab to find clues about Mitsuki. After evading the ninja guarding the entrance, they get in. But what they observe at the facility and hear from Orochimaru makes Boruto realize that he never truly knew Mitsuki. Meanwhile, the village finds out that Boruto and Sarada have gone in search of Mitsuki, and Shikadai and his Team 10 are assigned a tracking mission to bring back them back.

Orochimaru tells Boruto and Sakura about the White Snake Sage who lives in Ryuchi Cave. On their way there, the two are confronted by Team 10, which is determined to take the two back to the village so that they are not labeled as "rogue" ninja. But there's no way Boruto or Sarada will oblige until they find out the truth from Mitsuki, so they are forced into confrontation using everything they've got!

Boruto and friends head for Ryuchi Cave in order to see the White Snake Sage. But it's not a simple task, since they have no clue where it is. They search for miles, becoming hungry and tired. They are near their limit when Ryuchi Cave suddenly appears before them along with mysterious women to guide them. They are told they must pass a series of tests in order to meet the White Snake Sage!

The White Snake Sage tells Boruto to bring back the "Reverse Scale" from Garaga, a troublesome snake. Boruto and his friends head deeper into Ryuchi Cave and are confronted by a giant serpent. It is Garaga, the very one they seek, but its sheer power has the gang backed into a corner. Meanwhile, Moegi reports that Mitsuki's disappearance might involve someone who has access to crucial village secrets.

Boruto and the others work together to obtain the Reverse Scale from Garaga. But the battle proves difficult, as Garaga has the power to sense the location of its enemies and turn them into stone. In the midst of battle, the team notices inconsistencies in Garaga's moves and comes up with a successful strategy to subdue him. Boruto is seized with a strange feeling and makes Garaga a proposition.

Mitsuki heads toward Kokuyou and Sekiei's homeland, the Land of Earth. Meanwhile, thanks to the power of the White Snake Sage, Boruto and the others learn that Mitsuki is with Hidden Stone Ninja, and they also head for the Land of Earth. Each side has their own agenda, but will they be able to meet up successfully?

Kokuyou confronts Boruto and the others. Kokuyou, whose only goal is to become strong, is so powerful that he's taken down the Leaf ninja pursuing Mitsuki. He easily drives Boruto and his team into a corner. Just then, backup appears. Boruto and his friends manage to overcome Kokuyou, and finally catch with up Mitsuki.
