It's the beginning of World War II and the Japanese are closing in on Northern Australia. People are ordered to evacuate as soon as possible in case of aerial attacks. The people of Australia are wrought with panic and fear, uncertain of an imminent invasion. Suddenly the government brings in a Scorched Earth policy: a devastating military strategy whereupon people are forced to destroy anything that might be useful to an invading enemy. Dan McAlpine (Chips Rafferty) is a farmhand who rebels against the government's strategic operation and refuses to kill his livestock. Instead he decides to risk his life by leading his immense herd of cattle beyond civilisation and into the hazardous terrains of the Ozzie outback. It's a deadly journey that will take him 1600 miles across the continent, amidst unforeseen terror, suspense and bravery.
