A land of superlatives, Australia is the world’s largest island, the flattest and most arid territory on the planet. Its geographic isolation and its extreme climate have fashioned an uncommon topography where barren stretches of land no longer scare anyone. Thus this railroad, built in the heart of the Nullabor Plain - 200,000 km2 of semi-arid calcareous earth with barely a tree in sight. It takes three days to cross the 4 352 kilometers which separate Sydney from Perth; three days during which Emmanuelle Han will meet with singular characters, between madness, modernity and the outback spirit.
