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 trees 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, although Gina doesn't like it when he tries too hard for popularity, and briefly forgets her. 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 they are poisoning his already sick daughter, Princess Ida. The King, along with most of his army, die drowning while attempting to reach the "promised land" on the other side of the poisonous lake when it was frozen. Sebastian believes his plan has worked, but the governess (who was giving the princess the poison) is given it herself by Gina and the one remaining soldier, however it is believed she is tough enough not to die, but will remain a "sleeping ugly". The film ends with Sebastian and Gerard in cages, Princess Ida as the new queen and Kom and Gina returning to the land of the Woonkos, while it is clear that the two tribes will unite. It features the song "We Are One" by Westlife.
