A study of the sophisticated process of sweet potato horticulture developed by the Dani. The film follows the Dani sweet potato cycle from clearing off the old brush and weeds from a fallow field to planting, harvesting, cooking, and eating. At that time the Dani had the simplest of tools - long pointed wooden poles used as digging sticks that are hardened in the fire and soaked in water - and they still used their stone-bladed adzes. (By now, most Dani use steel shovels, axes, and bush knives and make stone adzes only for the tourist trade.)
