Double Take

Set at a school that gives lots of homework, the children are growing up as all school children do.
The innocence of childhood is a precious thing, and this school understands that.
Then a premeditated crime happens and the adults spring into action to deal with it.
So how can they deal with the corruption that led up to that moment?
How much evil will some people ignore before they're forced into action?
In any setting human nature remains the same.
Even with the bad ones that move among us.
