In some fanfictions, Naruto saves Sasuke from a self - destructive path. For example, Sasuke might be on the verge of sacrificing himself to defeat a common enemy. Naruto arrives just in time, and through their strong bond, he manages to stop Sasuke. They then team up and use a combination of their powers that they've developed over the years to defeat the enemy. It could also be that Sasuke is being manipulated by an unknown force, and Naruto has to figure out how to break the control and save him.
One possible plotline could be that Naruto has to go through a series of dangerous trials in the enemy's territory to reach Sasuke. He might face powerful foes and have to use new jutsu he's developed. Another plotline could be that Sasuke is in a coma, and Naruto uses his chakra to somehow enter Sasuke's mind and fight off the inner demons that are keeping Sasuke trapped. Maybe Naruto also has to convince Sasuke's friends from his time away to help him in this rescue mission.
A plot could involve Naruto traveling through time to save Sasuke. He goes back to a crucial moment in Sasuke's past when he made a fateful decision to leave the village. Naruto uses his knowledge of the future to change Sasuke's mind, preventing him from going down the dark path. This would require Naruto to be careful not to disrupt the timeline too much while still achieving his goal of saving Sasuke.
