While a boy is at camp he discovers the owner of the camp was a notorious bank robber and the boy wants to expose him but he doesn't want to get caught by the stingy counselors.

Sounds like a comedy but am not sure, what genre is this?

I do wonder though why the boy cares so much about the owner being a criminal. What is motivating him to turn him in? Is there a personal element in this for the boy?

Hope this helps.

Good revision. His real dramatic problem is that nobody's going to believe him. It's his word against that of the adults. So his objective goal has to be to find the evidence to make the cops believe him.

"When he discovers the owner of his summer camp is a notorious bank robber, a young camper must evade the corrupt councilors if he's to collect the evidence to put the owner away."
