Kayu, a young crocodile, is adopted by a family of spectacled-leaf monkeys in Manis Valley on the island of Langkawi. To remain in the valley and preserve the peace, he observes the Sacred Laws of the Jungle and learns to move through the valley unseen, hiding from the humans who have moved in when part of the rainforest is transformed into a holiday resort.  One day, Kayu overhears an evil plan and finds himself in a difficult situation: should he obey the Sacred Laws and not interfere with the affairs of humans, or should he save the life of a little girl?
