A is shocked, taking advantage, Naruto escapes. As team Samui and Mabui wake up, A tells to 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 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.

Trivia

 * Despite taking place after the time-skip, this movie drops the "Shippūden" in its official title.
 * In the movie, Naruto knows Killer B, but the Raikage still has his left hand, so it is hard to understand when the movie take place.
 * 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, a flintlock rifle, though none were seen being used so it is unknown if these were actually firearms or special weapons that had similar appearance to firearms.
