God that's a toughie; a lot happened even within Paris during the revolution; You mean throughout the revolutionary years? Again you just add key points like the king and his family being taken prisoner. But that's vague i have to say. I wish they could of given you more idea than that. I wouldn't be able to summarize so much in just 15 minutes. Talk about robespierre and the rise of the jacobins and their constant feuding and eventual rise to power etc; that kind of stuff. Hey i'd just stuff a lot of facts into it as much as possible.

Good luck though.
Hopefully you can come up with a way..
