Marcus leaves his home in Bluff and embarks on the start of a 100-day journey around New Zealand by rail. From Invercargill - the most "trained-up" place in the country - he catches a coal train to the tiny town of Ohai and stays with rail worker, and train painter, Tony Bishop. In Winton, Marcus investigates Minnie Dean's obsession with trains, then tracks down the old line to Lake Wakatipu and travels on the country's most famous train.
