Road to Sakura

is episode 271 of the Naruto: Shippūden anime.

Summary
As Ino strolls through the outlying forest of the village, considering what she should do on her day-off, she sees a bright light and hears a scream. Looking up she sees her friend Sakura falling through the sky. Rushing to her aid, as Sakura lay unconscious on a tree branch, Ino brings Sakura back to Konoha and has Tsunade check on her. Noting that Sakura had developed amnesia, a comical argument develops as Sakura unreservedly calls Tsunade's breasts gigantic (and voices the suspicion, that Tsunade enlarged her breasts artificially) and Shizune's underdeveloped which culminates in Ino having to stop them both from further hitting Sakura on the head, reminding them of her condition. As they go through the village, and encounter the other members of the Konoha 11, Sakura notes that they look vaguely familiar but not as how she remembered them. In an attempt to jog her memory everyone attempts to represent themselves the way Sakura remembers (which is the complete opposite of their current personalities), though this endeavour is ultimately unsuccessful. Later when Sakura realises that she had lost a pendant of a cherry blossom she had around her neck, she and Ino begin searching frantically for it. Her parents, Kizashi and Mebuki end up finding a dazed Sakura and her father returns the pendant, which she had dropped at their doorway, to her. Remembering parts of her past, Sakura runs to embrace her parents, crying. Though this puzzles her parents greatly, they depart telling her to come home later. Sakura ends up telling Ino that it was likely that she was not the Sakura she knew before disappearing again in a bright light, leaving Ino severely confused, wondering where was the Sakura she knew then.
