Wandering the deserted highways of an energy-starved dystopian Australia after eradicating the Night Rider's followers in 迷霧追魂手 (1979), the former patrolman, Max Rockatansky, finds himself roaming the endless wasteland scavenging for food and precious petrol. Suddenly, in the scorched wilderness, the hungry for fuel Max chances upon a small oil refinery; however, the place is under siege by Lord Humungus' barbarian horde of biker warlords, hell-bent on destruction and mayhem. Now, to get his hands on as much gas as he can carry, "Mad" Max will have to provide the defenceless community with a powerful truck to transport the gasoline to safety; nevertheless, this is easier said than done. Is Max, the battle-scarred Road Warrior, up to the task?
