Sebastian Valmont (Ryan Phillippe) is hit by a car and killed. At the school’s memorial service, Annette (Reese Witherspoon) and Cecile (Selma Blair) give out copies of Sebastian’s journal, which shows that Kathryn (Sarah Michelle Gellar) is to blame for everyone’s misery, and indirectly, to Sebastian’s death.
Read the source novel, Les Liaisons Dangereuses by Pierre Choderlos de Laclos, on-line here, here or here (if you can read French, that is. I haven’t found a freely-available English translation yet)
