The setting is Lake Victoria, Tanzania, the world's biggest tropical lake, and the Nile Perch (artificially introduced by man) has voraciously destroyed every other species of fish unfortunate to cross its path. Most of those lucky enough to have jobs, fish on the lake and sell their catch to be exported far away to Western Europe. None of the locals can afford to eat the meat of the Perch themselves. Prostitution, drug addiction and HIV are all rife. Large groups of orphaned homeless children sleep rough on the streets at night. And the vast "empty" cargo planes arriving from Europe actually seem to be (illegally) laden with weaponry to be sold onto the genocidal wars in Africa.
