The film premiered on 6 December 2014 and became the highest-grossing film in the franchise, before being surpassed by its sequel Boruto: Naruto the Movie.
Two years after the Fourth Ninja World War and Kakashi Hatake becomes the Sixth Hokage, the moon is falling towards Earth and will soon collide. The crisis is caused by Toneri Ōtsutsuki, a descendant of Hamura Ōtsutsuki of the Branch House, who is determined to fulfill his legacy and punish mankind for abusing chakra over a millennia. During the Rinne Festival, as Hinata Hyuga knits a red scarf that Naruto Uzumaki wore when they first met, Sakura offers to help her, but Hinata becomes doubtful as Naruto receives various gifts from everyone, including another scarf. Toneri infiltrates the Leaf Village but fails to kidnap Hinata due to Naruto's intervention, though Toneri successfully kidnaps Hanabi, Hinata's younger sister.
Naruto, Hinata, Sakura, Sai and Shikamaru Nara are assigned to rescue Hanabi after Kakashi gives a special clock to Shikamaru that counts down to doomsday. Traveling in an abandoned village of the Ōtsutsuki Clan, Naruto understands the concept of romantic love from watching Hinata's memories while being caught in a genjutsu and from spending more time with her. Toneri transplants Hanabi's eyes in himself to awaken the Tenseigan that his ancestors sealed over the last millennium and proposes to Hinata. To have a chance at saving Hanabi, Hinata accepts his offer after rejecting Naruto's love confession, which causes Naruto to fall into depression. Back on Earth, the villagers defend themselves and intercept the moon's meteorites, evacuating the civilians from Toneri's genocidal assault, while Sasuke Uchiha returns to protect the village.
After recovering for three days, Sakura reassures Naruto that Hinata truly loves him, and the group approaches Toneri's castle. Earlier, the spirit of Hamura contacts Hinata as the "Byakugan Princess", explaining that Toneri has misinterpreted his decree. Toneri refuses to listen to Hamura, ruins the scarf and brainwashes Hinata. Invading Toneri's castle, Sakura and Sai secure Hanabi, while Shikamaru holds off Toneri's puppets. Naruto saves Hinata from the ceremony and helps her destroy the Tenseigan altar. Toneri uses the remains to strengthen his power and slices the moon in half, as Naruto engages him in the Nine-Tails chakra mode. Naruto grasps a shred of the scarf and overpowers Toneri, making the moon return to orbit. Taking back Hanabi's eyes, Toneri realizes the truth about Hamura's decree and decides to stay on the moon to atone his sins. After Naruto tells Hinata that the scarf he wore earlier belonged to his late mother, the two confess their mutual love and return home.
During the end credits, Naruto and Hinata get married, while his friends attend the wedding. In a post-credits scene before the series' epilogue, the couple have two children, Boruto and Himawari.

Amy McNulty of Anime News Network, while criticizing the unengaging villain, overarching plot and score for having no impact, praised the top-notch animation and story for taking a more character-driven romance approach to it than previous films, concluding that "Despite the (awkward) title, the movie is not actually the final film in the franchise, but it's the last of an era and a fitting capstone for the series and its fandom." Charles Solomon of the Los Angeles Times gave the film a positive review, saying that "If 'The Last' lacks some of the emotional punch of the previous feature, 'The Road to Ninja,' Kobayashi compensates with flamboyant visuals that mix CG, drawn animation and elegant calligraphic figures, fans should stay through the credits for a surprising final scene." Naruto's romance with Hinata earned multiple positive reactions from the media to the point some wished The Last to be condensed so that their relationship was the main focus of it.
