The episode starts off with the Shinobazu breaking into a house and killing everyone in a room. They go to a hallway and break down a door. Then they hear a cry in a room. Gantetsu is ordered to check it out, and he kills the kid who is crying. The leader then starts a fire and burns down the house.
Lee and Naruto are training together. Naruto uses Tajuu Kage Bushin no Jutsu and surrounds Lee. Lee destroys Naruto's clones, but he makes more. Sakura comes running looking for Naruto and Lee. They both punch each other in the face and fall down. Sakura puts band aids on their wounds and tells them that they are wanted for a mission.
Tsunade tells Naruto, Sakura, and Lee to escort a shinobazu, Gantetsu, and they accept
Naruto, Sakura, and Lee come to the harbor where they will take a boat to the Forest Country. They then meet Suzumi, who will command the envoy, and they meet the escort unit. The unit surrounds parts of the ship. Then Naruto, Sakura, and Lee meet the unit leader, Captain Todoroki, who gives them a rude welcome saying they won't need their help. Naruto and Lee protest but Sakura tries to calm them down. They load Gantetsu on the ship and set sail.
Later that day while on the ship, Naruto and Lee complain about there being nothing to do and wish the shinobazu would attack so they show off their skills. Sakura tells them not to think like that because they have to get Gantetsu to the Forest Country safely. After Lee sides with Naruto and says he is bored, Sakura agrees too. Then they all sigh. Naruto, Sakura, and Lee then cook ramen and eat. After Naruto finishes his ramen he sneaks into the cargo to guard Gantetsu. Once he gets there he notices Todoroki in the back.
It then goes to a flashback of q burning house. Todoroki rushes to the back of the burning house looking for his mother and father and finds Gantetsu holding his brother. The house collapses on them as Todoroki calls out his brother's name: Akio!
Todoroki then backs up in anguish after his flashback. He curses at Gantetsu, and looks at a fish key-chain on his sword and says his brother's name. He then promises that he will avenge his brother. Todoroki pulls out his sword and tries to kill Gantetsu but Naruto stops him.
The other shinobazu close in on the ship. They then create a fork in the river and Sakura points it out.
Naruto questions Todoroki about why he was going to kill Gantetsu, but he denies it and says he is guarding him. He then says Gantetsu killed his people. One of the Shinobazu then cuts the boat in half. One half carries Naruto, Todoroki, and Gantetsu to one side. While the crew, Sakura, and Lee are carried into the fork. The shinobazu land on Naruto and Todoroki's half of the boat. The leader, Shura, then pulls out his umbrella and says he will take Gantetsu and Naruto says he will not let him.
