Max Rockatansky returns as the heroic loner who drives the dusty roads of a postapocalyptic Australian Outback in an unending search for gasoline. Arrayed against him and the other scraggly defendants of a fuel-depot encampment are the bizarre warriors commanded by the charismatic Lord Humungus, a violent leader whose scruples are as barren as the surrounding landscape.

For years, UFO sightings have been documented around the world. What were once mere sightings have now become brutal attacks of epic proportions. As the human race faces total annihilation with every major city destroyed only Los Angeles remains. Left with the task of saving humanity from extinction, a group of cowboys is the world s last stand in this Alien Armageddon.
