This is a good questions that should really be answered with a FAQ section.

Summarization is not something that Document Q&A is meant for. "Chat with your doc" = Q&A. A question is embedded along with every paragraph in the document to find a similarity match. Unless there is a paragraph discussing a word related to "plot" it will not have a useful answer. And as you found below, it is more than capable of hallucinating an answer outside the document (because it was not prompted properly to ONLY answer using the context of the document).
