Since I don't have access to this particular fanfic, it's hard to give a detailed account. However, generally speaking, in a fanfic where a character like Buck from '911' is falsely accused, it often serves to create drama and tension. The story might explore how Buck deals with the false accusations, how it affects his mental state, his friendships, and his standing in the community or among his colleagues. It could also be a vehicle for exploring themes of justice, truth, and redemption as Buck tries to clear his name.
In many such fanfictions, Naruto is initially hurt by the false accusations, especially if they come from his friends or the people he trusts in the village. But then, his strong will kicks in. He starts to analyze the situation carefully. He may talk to people who are neutral or try to find contradictions in the false accusations. He uses his ninja skills not just in combat but also in detective - like investigations to clear his name.
One example could be a fanfiction where Naruto is wrongly accused of stealing a powerful jutsu. In the story, perhaps a rival village's ninja frames him by planting false evidence at the scene. Another could be a situation where he is falsely accused of being a spy within his own village due to some misunderstandings and false testimonies.

Love in the face of adversity is another theme. Despite the false accusations, the heroine often finds love. It could be with a man who initially doubts her but then comes to believe in her innocence. This kind of love story set against the historical context is very appealing. In many such novels, the historical period also plays a role. The social norms and power structures of the time can either be part of the problem causing the false accusations or part of the solution in helping the heroine clear her name. For instance, if it's a time when women had few rights, it makes her fight for justice even more difficult but also more heroic.
