Kilo is a Dourou. He lives in Taboun, a small village of about a hundred inhabitants, lost in the middle of the huge savanna of northern Cameroon. This year, a bush fire destroyed a large part of Kilo's cotton crop. His eldest son, Gibi, who is eleven, has been promoted to a class in which the chalk and slate board he has used up to now have to be replaced by notebooks and textbooks. The only possibility for Kilo to meet this new expense is to capture a python and sell its skin. But the giant snake is a feared devil… One needs a lot of courage and magic to confront him!
