Arthur Williams visits the island of Wadigi, part of the Fiji chain, as he continues the series exploring some of the planet's most remote places. Tracey Johnson has turned the island into a bolthole for the super-rich, but she only leases the island from its traditional owners - Tia Ratubuli and his family. Tia teaches Arthur to catch leatherjacket fish by hand from the coral reef. Flying on to the island of Koro, Arthur meets Marianna, whose village was recently devastated by a cyclone. On the islands of Vanuatu, flying doctor Mark Turnball takes Arthur on his rounds. Finally, Arthur attempts to land on the slopes of an active volcano.
