Kom is a member of the Woonkos, a tribe of monkeys who live in a canopy and they live in obsessive fear of falling into a nearby pit, which is inhabited by other monkeys they believe to be demons. Kom refuses to believe these superstitions and claims bravery and is rude to the elder of the Woonkos. However, on the way home, he accidentally falls from the tress into the land below. When there, he meets the Lankoo tribe and finds they are in fact very similar to his own tribe. He befriends Gina, a young maid and Master Martin, the librarian and they help teach him to behave like a Lankoo. The Lankoo king is impressed by his actions. However, there is also evil afoot. The chancellor Sebastian, the governess and their dim-witted side-kick, Gerard the Gormless, are up to evil plans: they will find a way for the King to die and
