The second stage of Naruto's training continues, while Tsunade sends out twenty teams composed of four ninja each to deal with the Akatsuki members in the Fire Country. Shikamaru leaves with Asuma, Izumo and Kotetsu, whereas Ino and Choji leave with Raido and Aoba. After putting in considerable effort, Naruto clears the second stage of his training, but collapses from hunger and exhaustion almost immediately afterward.

With careful planning, the group manages to find and trap Hidan and Kakuzu. However, things seem to be going a bit too smoothly.

Kabuto and Yūkimaru travel to a lake, where Kabuto attempts to draw out a mysterious creature. Guren branches off from her men to find Orochimaru, who has Sasuke fight an army of Sound Ninja as training. Sasuke defeats them all, but declares that he wants to kill Itachi more than them. Naruto continues his training by summoning Gamakichi and Gamatatsu, but still doesn't understand the concept of connecting to another person's heart. Kabuto and Yūkimaru arrive at the Hot Springs Village where Naruto and Jiraiya are.

Guren is rendered unconscious and relives her past as Naruto is caught in an illusion about Sasuke. After Kakashi finds him, Teams Kakashi and Kurenai conclude the mist around them causes Genjutsu courtesy of the Three-Tails. After Guren wakes up, Yūkimaru suffers another fever and passes out. Tsunade hears of the Three-Tails and assmbles Shizune, Ino, Tenten and Lee to go and seal it before the Akatsuki do. Naruto and Sakura talk about the home that people should return to before Naruto heads off to find Yūkimaru.

Yukimaru informs Kakashi and the others to Naruto and Guren's whereabouts and they attempt to free them with Yukimaru's help. Kiba, Tenten and Lee once again battle Kihou, Kigiri and Nurari after gaining more power from Kabuto. Naruto and Guren continue to search for a way out, coming across human-sized Sanbi-like creatures and illusions. Will Naruto and Guren ever find a way out?

The second member of Sasuke's team is revealed to be a woman named Karin. After Sasuke and Suigetsu arrive at the Southern Hideout, Sasuke requests that Karin comes with them. Despite her hesitations and quarrels with Suigetsu, Karin ultimately accepts after remembering her very first encounter with Sasuke. Sasuke orders Suigetsu to release the prisoners, and after that, they set off to recruit the final member of the team - Jugo.

As a child, Sasuke craved attention from his older brother Itachi. Sasuke and Itachi have a chance to spend some time alone when their parents are away. Meanwhile, Sakura is very shy and tends to spend her free time by herself. One day, her new friend Ino gives her a present.
