KATO, is a chimpanzee raised in captivity, and star of the Darwin Research Institute's sign language program in Santa Barbara, California. He is returned to the African jungle where he was born, following a 'Free Kato' campaign in the media. Introduced to a colony of wild chimpanzees in Tanzania, KATO uses skills learned from his human handlers to overthrow the alpha male, before leading his new 'family' on a quest. A quest which becomes a rampage. Will he survive the Tanzanian army's bid to capture him?
