Walkabout (1971)

Under the pretense of having a picnic, a geologist takes his teenage daughter and 6-year-old son into the Australian outback and attempts to shoot them. When he fails, he turns the gun on himself, and the two city-bred children must contend with harsh wilderness alone. They are saved by a chance encounter with an Aboriginal boy who shows them how to survive, and in the process underscores the disharmony between nature and modern life.

Walkabout keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder.
