In case you are curious, this is the plot outline from the URL above:
A story about a boy called Benny, who watches violent movies, including a
home-made video of a pig being slaughtered. Soon after, Benny loses his mind and
kills a girl and films the murder with his video camera.
Actually, this outline is not even half the story (I just didn't find any better
one in English, and the Babelfish translation of the German plot descriptions,
e.g., at http://ourworld.compuserve.com/homepages/berunge/bennys.htm sucks).
Anyway, what comes after the killing is the more important part.
