Mechanic Barry lives in the Australian outback with his wife Annie and daughter Meganne. During a meteor shower, Barry's sister Brooke is attacked in her Bulla, Victoria studio by her model and her assistant, who have suddenly become zombies. She calls Barry and warns him to get out of the city. He, Annie, and Meganne don gas masks and fight their way to the family car. When Meganne and Annie remove their gas masks they become infected and zombify, and Barry is forced to kill them with a nailgun. He runs out of nails before he can kill himself.
