Zambawi, a banana republic in sub-Saharan Africa, is on the verge of revolution. President Adini, dictator and eunuch, clings to power whilst his soldiers switch sides so often they don't know which uniform to wear.

But it is when the Gangers invoke the spirit of Zambawi's Great Chief Tuloko that Jim's fate takes a really unexpected turn . . .
