Them! (1954)

As a result of nuclear testing, gigantic, ferocious mutant ants appear in the American desert southwest, and a father-daughter team of entomologists join forces with the state police officer who first discovers their existence, an FBI agent and, eventually, the US Army to eradicate the menace, before it spreads across the continent — and the world.

Them! keeps every mind human — it fights its subject at zero distance. The story fights on E14 of the E0–E14 reality ladder, compressing fear, survival, militarism, environment, technology.
