"White Zetsu's Trap" (白ゼツの罠, Shiro Zetsu no Torappu) is episode 279 of the Naruto: Shippūden anime.
Team 8 from Konohagakure is sent to investigate a suspected breach of the Allied Shinobi Forces perimeter and encounters a cave filled with enemy White Zetsu Army forces. Engaging the forces, Hinata sends out a messenger owl to the Sealing Team and she alongside, Shino, Kiba, and Akamaru, hold off the opposition until the team can arrive and seal the cave. When the two members of the sealing team arrive, they immediately begin the process to seal the cave, however, as Team 8 escapes, White Zetsu clones follow, forcing Kiba to attack them. In the process, a lamp is overturned and it lights a trail of oil leading to several crates of explosive tags. With Akamaru unable to douse the flames, the crates explode. Finding one of the two shinobi from the Sealing Team dead, the team quickly uncovers that he was killed after the explosion by an external wound. Mistrust, as to whether the people before them were who they really said, soon starts to spread. When deciding to part ways and search for the next person, a scream is heard. Rushing to the location, they find him dead, clutching a piece of Shino's coat. This leads to even more discourse amongst the team, which ultimately decides to settle things with rock-paper-scissors with the loser being questioned about personal information. When Shino is thought to be the culprit, the other three take him down only for Hinata to be revealed as the impostor. It was, however, revealed that Kiba and Shino had planned this all along using hand signals during rock-paper-scissors and clones to draw out the real culprit. With the enemy uncovered now, Shino attacks him with the Secret Technique: Insect Tornado. Having a brief squabble about Kiba's willingness to attack him, the three set out and eventually find Hinata who was unconscious. Discussing what had transpired, the team's drive to destroy the enemy is renewed after they realise that the enemy had been using Yamato to gain personal intel on them; Yamato seemingly has been keeping secrets for each member of the team.
