Welcome to the school of hard knocks

A group of teachers must defend themselves from a gang of murderous kids when their school comes under siege after hours.
F keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
