Plot of Naruto:Shippūden

Summary
Starting out as a mission to capture the missing-nin Itachi Uchiha, it called for the squad to split up and search the area for any sign of Itachi. However, upon seeing Deidara's suicide explosion, the team regrouped, with Kiba finding Sasuke's scent. With Sasuke so close, the squad's primary mission of finding Itachi was replaced with finding Sasuke instead. The squad engaged in battle with Tobi of Akatsuki, but couldn't land a single hit on him. Zetsu appeared and told Tobi about the outcome of the battle between Itachi and Sasuke, and both Akatsukis leave. The 8-Man Squad was able to find the place where the battle between Sasuke and Itachi Uchiha had happened, but didn't find any of their bodies, since they had already been taken by Tobi.
