Tension fills the air as the team's water-logged cargo boat begins to sink on the way to Borneo. With the boat out of action they find another way, and eventually arrive with the vaccines in a village up the Pawan River. After a stop off in Bali, Charley embarks upon a series of boat journeys navigating his way across the Indonesian archipelago. From speedboats to hand built traditional phinisi boats, he makes his way to Kupang and, finally, Australia for the final leg of the journey.
