Welcome to the Village Hidden in the Leaves, where deadly serious ninja roam the land and the seriously mischievous Naruto Uzumaki causes trouble everywhere he goes. But when he steals the ancient scroll of sealing, he unleashes a rare power rarely seen in a 12-year-old boy!
On the way to becoming a ninja, Naruto must team up with his classmates, the pretty Sakura and the pretty serious Sasuke, whose only common bond is that they both hate Naruto. So Naruto tries to win Sakura over by pretending to be her life-long crush ...Sasuke!
The recently formed Team 7 (Naruto, Sakura and Sasuke) meet their instructor, Hatake Kakashi, and begin training to see if they pass to the next stage of ninja training. The three young ninja students meet Kakashi and they go off to train. Kakashi tells them to engage in the following exercise: try and take two bells away from him using their ninja knowledge...
With the threat of failure hanging over their heads, Naruto, Sasuke and Sakura try everything they know to pass the grueling survival test. But it will take some wise advice from Kakashi to teach these selfish ninja a thing or two about teamwork.
Naruto and his squad start their first ninja missions with boring and menial tasks. Weary and angry, Naruto vents his frustration at the Hokage. Amused by Naruto's excitement, he gives them a new mission, to protect a grumpy old man named Tazuna as he returns to his home!
Naruto and his squad arrive in the Land of the Waves and learn that an evil businessman named Gato has taken over the land. Zabuza Momochi appears, hired by Gato to kill Tazuna. Excited and ready to attack, Naruto can't wait to take on this powerful ninja assassin. Will he be up to the challenge?!
Kakashi has the upper hand in his battle with Zabuza. But the tide turns when Kakashi is trapped inside Zabuza's Water Prison! Kakashi urges the squad to flee, but Naruto remembers the pledge he made--to never run away again--and holds his ground!!
Recuperating at Tazuna's house, Kakashi is dissatisfied with the outcome of the battle. He concludes that Zabuza isn't dead and the young tracking ninja helped Zabuza escape! Kakashi decides to implement some interesting training that will allow Naruto, Sasuke and Sakura to better control their chakra!
Sakura goes into town with Tazuna and sees the hardships that the people of the Land of Waves suffer under Gato's rule. This is the reason Tazuna is risking his life to build a bridge that crosses the ocean. With a bridge that gives everyone access to other lands, people will no longer have to rely on Gato, who controls all imports. Meanwhile, Naruto and Sasuke continue to train, using chakra to climb a tree.
While Naruto concentrates on the training to control his chakra, a mysterious person suddenly appears before him. The person tells Naruto that as long as one has the desire to protect what he loves, there is no limit to becoming stronger. The mysterious figure echoes the sentiment inside Naruto and the two feel a sense of connection.
Once again, the time has come to fight Zabuza, and this time he's got company -- the tracking ninja who supposedly killed him. Zabuza and his companion take notice of Sasuke's abilities, and Sasuke in turn realizes the immense power that the masked ninja holds. As if they were meant to fight each other, Sasuke and the masked ninja begin to battle.
