Plot
The film starts with A discussing a box with Omoi, Karui, Samui and Mabui, when suddenly gas covers the room knocking everyone asleep. Then a hooded figure leaps out attacking the sleeping Raikage, only for the figure to stop right before killing A. When A is seen above the figure, the figure dodges, and is able to fight equally with A. In the battle A is able to destroy the hood, revealing the hooded figure as Naruto Uzumaki. A is shocked, taking advantage, Naruto escapes. As Team Samui and Mabui wake up, A tells them to summon Killer B.

In Konohagakure, Tsunade states that Naruto is wanted for attempting to assassinate the leader of Kumogakure, the Raikage, and killing jōnin from Kirigakure and Iwagakure to Team Kakashi. Naruto and Sakura refuse claims, but Tsunade states Naruto will be placed in Hōzukijō, a criminal containment facility, also known as the "Blood Prison", in Kusagakure. Naruto attempts to escape, only for Yamato to encase him, and Tsunade takes away his forehead protector. When Naruto arrives at Hōzukijo, Mui, the head of the prison, quickly places the Fire Release: Heavenly Prison on Naruto, sealing his chakra. Naruto learns this the hard way after using his shadow clones, Naruto quickly collapses from the pain caused by the seal. Naruto is eventually taken into a cell, where he puts one of his clones to replace him, and meets an ally of Bee who helps him escape. Naruto escapes and meets Ryūzetsu, who helps him when he gets drowned and talks to him about Muku and Mui. Naruto, goes against Mui again, but fails and is sent to the punishment room. In the punishment room, Naruto sets a shadow clone to gather some natural energy, since he intends on going Sage Mode.

However, Naruto is eventually caught and has some of his chakra extracted from him. He eventually escapes, but sees that Mui intends on bringing back his son, muku. Muku is brought back, but he knocks Mui unconscious, by impaling him and kills Karon. Naruto enters Sage Mode and then tried to use Oodama Rasengan on the Box of Ultimate Bliss to destroy it but fails. Naruto then is engaged in combat with Satori who defeats Naruto's shadow clone. With Naruto unable to touch Satori he then states to fight a monster, one must use a monster and summons Gamabunta to help combat Satori, but they can't attack him, due to their moves being predicted before-hand. Eventually, Gamabunta gets defeated and Killer Bee defends naruto from being attacked. Naruto decides to attain Sage Mode once more and tells Killer Bee and the others to distract Satori, while he does this.

When in Sage Mode, Naruto is able to fight Satori evenly, but both him and Ryūzetsu get impaled, by Satori. Mui wakes up and stops his son, while Naruto defeats Satori by firing a Wind Release: Rasenshuriken and returns Satori back to normal. Muku kills Mui before killing himself, while Ryuzetsu revives Naruto, by kissing him, but at the cost of her life.

In the aftermath, Mui and Ryuzetsu is shown buried next to each other. Naruto ties Ryuzetsu's bandanna around her gravestone.

Trivia

 * Despite taking place after the time-skip, this movie drops the "Shippūden" in its official title.
 * The timing this movie takes place is very uncertain as story elements present in the proper story are present while others are not, such as;
 * Naruto knowing Sage Mode, despite the fact that Konoha was not destroyed by the Invasion of Pain.
 * A still has his left hand, despite losing it not long after the Invasion.
 * Naruto knew Killer B, but did not meet him until their training at the Island Turtle.
 * Despite the fact that Masashi Kishimoto mentioned that the world of Naruto will not have any firearms, there were plenty of Blood Prison guards holding firearms, such as a flintlock rifle, though none of them were ever seen to be used.
 * Unlike the anime/manga, each time Naruto entered Sage Mode, the red coat he wore against Pain would appear on his person for no reason, and would disappear when he exits the mode.
 * The forehead protectors that Muku and Ryūzetsu wear shows the Kusagakure symbol with four blades, although the actual symbol contains only three.
 * The sculpture shown in the castle itself is the Ecstasy of Saint Theresa by Bernini, which illustrates a moment where divinity intrudes on an earthly body.
