Ghosts from the Past

is episode 303 of the Naruto: Shippūden anime.

Summary
With the Allied Shinobi Forces on high alert because of the imposters within their midsts, their worries are further added to when Otogakure's Sound Four is reincarnated on the battlefield. The members of Konoha's disbanded Sasuke Retrieval Team, however, make short work of these opponents, displaying just how much they had grown over the years despite the amplification of their opponent's cursed seals. However, the Alliance's cheers of victory are soon stifled as a seal activates around the defeated shinobi and Kiba Inuzuka, Akamaru, Shikamaru Nara, and Chōji Akimichi. Elsewhere, as he moves towards the location, Naruto senses the malevolence on the battlefield and rushes towards his friend's location.
