Naruto Shippuden: The Movie - The Will of Fire

Four ninjas with bloodline limits who have been guarding the Hidden Villages of Cloud, Stone, Mist and Sand disappear from their respective villages. The Land of Fire comes under suspicion as it is the only country to have suffered no loss. Mounting suspicion among the four countries almost brings about a fourth Great Ninja War. Is someone from the Leaf Village behind all of this? Could it be the infamous copy ninja Kakashi?
