In East Africa, animal species of extraordinary variety coexist, mingle, and examine each other with indifference. Everything is nothing but an immense movement for food.

Movements become flights, pursuits, leaps, collapses, while stillness becomes waiting, watching, and worrying. Thus revealed, the nocturnal world breaks with the long continuity of day.
