can someone help me?

ok, so we are watching this movie in french class...it is pretty good, but french is boring and i dozed off for a little and i have no idea what is going on...

see, since it is in french, i couldnt listen while i dozed off, and sometimes i missed the subtitles

we have to write a summary of what happened in the movie, where, and all that crap...can someone please give me a detailed summary of the movie...like everything...all i know is the actress killed some guy and mr. auger got blamed for it or something, i dont know...like i have no idea what all that crap about heavy water is...anyways...id love it id someone wrote a summary for me (you dont have to do it in french...haha)

thanks
