The two children have the clothes on their backs, some meagre rations of non-perishable food, a battery-powered transistor radio, the son's satchel primarily containing his toys, and a small piece of cloth they used as their picnic cloth.
They encounter a Yolŋu boy (a young David Gulpilil) who is on his walkabout, a rite of passage into manhood where he spends entire months on his own living off the land. The boy helps them to survive but doesn't understand their need to return to civilization. A towering work, painted from a palette of feelings and instincts words cannot do justice to.
