The wonderful story of an astonishing friendship: that of Fonabio, a young boy from black Africa, sensitive and generous, and of Naba, an orphaned lion cub. The village where Fonabio shares the hut of the sorcerer Tiemoko is calm and peaceful; only the buffalo, elephant and panther hunts marked in the course of time. And then there is Marlow, the planter, whose powerful personality excites the child who devotes a true cult to him. With Naba and the white man, how beautiful life could be! ...

But in the bush as elsewhere, fate ties its net of contradictions and trials. One day, in dramatic circumstances, Fonabio, his heart torn between his two friendships, one day Fonabio will have to choose.
