Orochimaru, a former student of the Third Hokage that is eager to kill his old master, resurrects the First and Second Hokage, the Third's former teachers, to fight him. Needing to get rid of the two if he is to defeat Orochimaru, the Third seals away their souls. The Third attempts to seal Orochimaru's soul as well, but is stabbed in the back before he can complete the sealing. Elsewhere, Naruto, Sakura, and Shikamaru discover that they are being followed by some of Konoha's invaders, and Shikamaru opts to stay behind to stall them. Using the strength left over from his fight with Temari he buys them the necessary time.
