Lance Hackett, a geologist for Ayers Mining Company, has identified a promising location to search for uranium in the
Outback near
Coober Pedy,
South Australia. Explosives are to be used to analyze the "geological substructure of the region", so the local Aboriginal people block the work, as they claim the area is where the
green ants dream, and that disturbing the ants will destroy humanity. Hackett finds himself the intermediary between his employer and the tribe, and becomes increasingly sympathetic to the indigenous worldview and cause. Baldwin Ferguson, an executive vice-president of Ayers, is unable to sway the tribal elders with either a trip to
Melbourne or the gift of a large, green
military airplane that they ask for. The case goes to trial, and the judge decides in favor of the mining company. Two of the tribal elders take to spending their days sitting in the airplane, and one, Dayipu, is in it when Watson, a younger member of the tribe who learned to fly in the air force, takes it up to prove he can. The plane does not have much fuel, and Watson, who is drunk, crashes in the hills. Ayers begins their work, drilling test holes and setting off small explosives, but Hackett quits and goes to live in an old water tank offered to him by another white man who was profoundly affected by studying the local Aboriginal culture. ==Cast==
