The Ultimate Experience in Inner Terror.

A man tries to uncover an unconventional psychologist's therapy techniques on his institutionalized wife, while a series of brutal attacks committed by a brood of mutant children coincides with the husband's investigation.
The Brood keeps every mind human — it fights its subject at zero distance. The story fights on E8/E6 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.
