Plot Overview
Assigned on a mission to capture Mukade, a missing-nin, Naruto Uzumaki sets out for the once glorious historic ruins of "Ouran", where he pursues and corners the rogue ninja. Mukade's goal is revealed to be a dormant leyline within the ruins; he unleashes the power of the leyline, causing a light to envelop Naruto, sending him twenty years into the past. When Naruto awakens, he comes into contact with his father (the future Fourth Hokage, Minato Namikaze).

One trailer has shown that during this period, Minato was on a team with Shibi Aburame and Chōza Akimichi, seeking to intervene in the conflicts enveloping a place known as Rouran, with its princess Sarah in the middle of the crisis. A young Kakashi Hatake is tagging along with them. Sakura Haruno and Sai also appear to be involved in assisting Naruto in his efforts within the movie.

In the trailer, Naruto is seen wielding a wind chakra infused kunai and fighting unknown mechanical figures. Minato is seen also seen, interfering in the fight, aiding Naruto. He seems to be well aware who Naruto is.
