From the 'land of craters and caves' to the tropical waters of The Gulf of Carpentaria, Ted Egan is on the road again. This time the story begins at the Undara Lava Tubes which are tunnels created from the lava flows of ancient volcanos. Many of these flows went for hundreds of kilometres. This is the first time that the tubes have been extensively filmed. Travelling west from the coast Ted meets up with a fascinating range of outback characters. At Croydon, Pat Wilson runs a country store that is part shop and part museum. Col Shepherd drives the Gulflander, a unique railway service from Croydon to Normanton and Col Casey and his work gang keep the track open. Ted ends up at Normanton's annual bush race meeting and when his favourite horse runs second he decides to go fishing at Karumba, where the prawning fleet is busy at work. Later he meets up with another group of 'Outback characters', netting the delicious Barramundi, the most prized of fish. He joins the fisherman at a riverbank bar-b-que where they swap a few fishy stories.
