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. All in all, Zambawi is not the ideal location for student teacher Jim Tulloh to indulge in a spot of character building. Yet with the help of Musa, the local witchdoctor, some flatulent weed and headmaster, PK, Jim's days look set to be mellow in the extreme; until that is Jim is kidnapped from his bush school by the rebel Black Boot Gang. But it is when the Gangers invoke the spirit of Zambawi's Great Chief Tuloko that Jim's fate takes a really unexpected turn . . .
