Will and Bill travel to Borneo to meet the challenge of living with the Murat tribal people and to see if they can cope with their traditional, demanding way of life.

A huge animal lover, Will visits orangutans at a nature reserve. There he fulfils one of his life long dreams when he is allowed to handle and help care for the endangered species. As one of only four places in the world where indigenous orangutans are found, the species is an important part of Borneo's heritage.

Then, travelling through mountains and jungle, the Mellors arrive at the Murut settlement. Being a more sensitive type, Will finds the Murut lifestyle harder to acclimatise to than his father who is more of a man's man. They embark on a hunting excursion, tracking wild boar with the aid of dogs, machetes, spears and blow pipes.

Will and Bill also brush up on their survival skills, taking on the responsibility of fishing for the group's dinner, and building shelters to sleep in by night.
