Watch Nightmaster

A high-school science teacher suspects ex-soldier Steve Beck of tiring out her class and overexerting them during his early morning martial arts classes. She moves to have the classes stopped so the children can focus on learning, rather than training. Steve insists the classes are for the good of the students but both teachers find that it's the late night combat trial the children are designing for themselves that's causing the problem. They must work together to stop the children from becoming a paramilitary gang before they ruin their lives or worse, someone gets hurt.
