The Ghan runs 1,865 miles from Adelaide to Darwin, crossing South Australia's dry farmland, the red rock country around Alice Springs, and the tropical Top End over three days and two nights. The film follows the crew keeping the train running and its guests fed and entertained while the Outback throws up floods, brush fires, and long stretches where the nearest town is hours away by any other transport. Cameras go into the engine cabs, the dining car, and the control rooms where staff track weather and track conditions across a route with almost no infrastructure to fall back on if something goes wrong. Interviews with drivers, hospitality staff, and engineers explain what it takes to move a train this long through terrain this remote, from water supply to rail maintenance in extreme heat. The result is as much a portrait of the Australian interior as it is of the train itself, using the Ghan's fixed schedule as a way of showing how much the landscape can still disrupt a journey that looks, on paper, like a straight line on a map.
