Rock Lee challenges Sasuke to a one-on-one fight. Naruto grows angry and attacks him, only to be beaten in one attack. Sasuke realizes the challenge and eagerly accepts. But will Sasuke be defeated just as easily by this mysterious ninja? Sasuke's only advantage seems to be his Sharingan, but what happens when not even that will work?

Kakashi takes on Itachi, with both of them using the Sharingan. However, Kakashi soon realizes that he stands no chance against the legendary ninja. Itachi reveals that he has not come for his little brother, but instead he's come to do something else...abduct Naruto, and Kyubi as well!

After passing stage one of the training, Naruto moves into stage two: power training. Jiraiya realizes that, like him, Naruto has a hard time concentrating, so he paints a spiral in the palm of Naruto's hand to help him to focus. With the aid of the spiral and a quick flashback to Iruka-sensei, Naruto completes stage two. Meanwhile, Tsunade's luck has become uncommonly good, which worries her. After being talked into sightseeing by her assistant, Tsunade meets Orochimaru...and she doesn't look at all pleased.

With Tsunade still paralized with fear and Naruto being a low level ninja, it is up to Shizune and Jiraiya to defeat Kabuto and Orochimaru. Orochimaru and Kabuto summon two giant snakes while Jiraiya summons Gamakichi, who does nothing. Naruto tries to help Jiraya, but he too only summons a small frog that also does nothing. Orochimaru and Kabuto attack and Shizune is easily defeated. Naruto tries Rasengan but fails. Can he master the technique before Kabuto does anything to Tsunade? How far will he go to master it?

As Lee decides whether or not to go through with the operation, Gai decides to give him some motivation. Meanwhile, Tsunade frantically struggles to increase the operation's success rate.

Sasuke takes on all four Sound Ninja, but soon learns it's going to take more than Chidori to defeat them!

In pursuit of the Sound Ninja, Naruto, Kiba and Shikamaru strike at dawn to retrieve Sasuke and bring him back to the Hidden Leaf Village.

Naruto's Shadow Clones are no match for Kimimaro's attacks. But when an old bushy-browed buddy from the Leaf Village shows up, all bets are off!

While Naruto is busy underwater, Sasuke remembers the fateful day in which his clan was killed. He remembers why Itachi spared his life, and why Itachi did what what he did. Now, in order to gain the same power as his brother, he must kill his closest friend...Naruto!

Naruto, Sakura and Jiraiya end up in a town that is even worse than the one they were chased out of. Jiraiya heads off and leaves Naruto and Sakura to get some food. Along the way they find the ninja that attacked them before, but things are not as clearcut as they might seem.
