A desert wasteland.
Humans on the verge of extinction.
Teenagers Don and Janet run off to California to start a new life together. Along the way, they find themselves in a dangerous land. Did they inadvertently time travel to a future Earth? Or, a parallel universe?
One of the nomadic tribes they encounter rescues the young couple. These small groups journey endlessly, searching for food and water. The brutal leaders of the Ganu Camp take whatever meager supplies they discover. Yearning to break free from enslavement, they hail Don as their prophesied savior.
Now, faced with a lost-cause battle, the teenagers must defend their new friends with the only weapons available to them. How will they defeat a powerful enemy with only skyrockets, firecrackers, and a dog whistle?
