Well, the plot could be that Naruto is on a mission and stumbles upon a child in danger. Maybe the child is in a village under attack by bandits.

The fanfiction could start with the child being lost in a forest full of dangerous creatures. Naruto, being the hero he is, senses the child's distress.

After that, he takes the child back to the Hidden Leaf Village and the story could follow the child's journey of learning about the ninja world with Naruto as a mentor.
In this fanfiction, perhaps the child is a target of an evil ninja organization. Naruto discovers the plot and intervenes. He battles the powerful ninjas of the organization using his Nine - Tails Chakra mode. He manages to defeat them and saves the child. Then, Naruto helps the child reunite with his family and the story could end with the child looking up to Naruto as a hero and wanting to become a ninja like him one day.
