I remember watching this movie around 2 years ago I think it came out around then as well. It starts off with a teenager who I think name is Billy driving a stolen which he then crashes. He ends up in some prison type thing for underage offenders. A part of the movie features him getting better at American football. He’s portrayed to be a bad boy. He deliberately gets beat up so he can see the nurse who he fancies. He eventually escapes. At the end of the movie group or teenagers there put on a film show type thing outside where they create the backboard for the film to be protected on.
