Naruto Shippuden Movie 6: Road to Ninja
With the demon fox sealed away, things continued as normal. However, the peace of the village would not last long, for Pain, Konan, Itachi Uchiha, Kisame Hoshigaki, Sasori, Deidara, Hidan and Kakuzu — members of a dreaded shinobi group called the Akatsuki — attacked Konohagakure. Naruto narrowly manages to launch a counter-attack but why have these shinobi appeared when all of them were meant to have died? The mystery remains, but the shinobi are praised by heir families for completing such a dangerous mission. However, one of them who has never known the faces of his parents, Naruto, cannot help but feel lonely. At that exact time, suddenly, the masked man makes his appearance in Konoha. Naruto and his allies are both attacked by the man's mysterious new dōjutsu.
Note: I'm not sure if this is the plot of the movie because this sounds like it's describing the anime series.
