In this fanfiction, the plot could revolve around Sakura's experimentation with the container. She wants to find a way to use the Kyuubi's chakra to heal. So, she starts conducting tests on the container. But things go wrong when the Kyuubi's chakra starts to leak and affects Sakura's mind. She starts having visions of the Kyuubi's past and its previous hosts. With the help of her friends, she has to find a way to reverse the effects and also figure out a new approach to her research. This could lead to a whole new understanding of chakra and its healing properties in the Naruto world.
One plotline could be that the container holding the Kyuubi is stolen and Sakura has to track it down.

Well, perhaps in this fanfiction, the container is some sort of magical or high - tech device. Sakura, being the intelligent and strong - willed character she is, would try to understand the nature of the Kyuubi within.

It might lead to an unexpected alliance between Sakura and the Kyuubi, which could change the whole Naruto universe's power dynamics.

One possible plotline could be Naruto gradually losing control over his own actions as the Kyuubi's influence grows stronger. For example, he might start to act more aggressively towards his friends without realizing it.
Maybe Sakura is a healer in a small village. A gypsy arrives with a strange illness that no one in the village can cure. Sakura tries her best to help the gypsy, and in the process, she discovers that the gypsy has a unique connection to an ancient magic. This leads Sakura to learn more about this magic from the gypsy, which changes her life and the way she views the world around her.
Perhaps in a 'sakura is innocent fanfiction', there could be a plot where Sakura is in a new, unfamiliar world or situation. People there initially misjudge her actions as being malicious, but as the story unfolds, it becomes clear that she was just acting out of pure intentions and is truly innocent. For example, if she's in a magical realm where her normal, helpful actions are misconstrued as dark magic. The story could then focus on her journey to clear her name and show that she's just an innocent girl trying to do good.
In some fanfictions, it could be that Sakura is under a genjutsu (illusion technique). The genjutsu makes her act in ways that seem like she is cheating on Sasuke.
