So I believe this movie came out some time after 2000, but I could be mistaken. Anyways, the movie starts out with a bunch of kids who are being held. They get time outside in this courtyard area where there is a shed and a few other things. Also, the entire place is enclosed with a wall. So one of the kids discovers that you can climb onto the shed and from there they can get over the wall. So one night, all of the kids escape and steal a school bus. They go for a joyride into the woods. The three main boys decide that they won’t go back, but everyone else wants to. So the other kids return to the place, while the three boys try to live in the woods. I don’t really remember what all happens, but I know one of the boys gets really sick and ends up dying. I have been trying to find the name of this movie for years with no luck. Any help would be appreciated 🙂
