In the far future, a nuclear war forces the population of Los Angeles to retreat underground. Thinking life on the surface to be impossible, the survivors batten down for a longor possibly indefinitestay. They name their new home Low Angeles and begin to build lives underground. After over a century of work, they have created a city that even the Los Angeles of yore could not hope to emulate.

Jensen Stewart is an underachieving Low Angeles teenager from a supportive family. His average life is shaken to its core when he is accused of murder, a rare crime in modern day Low Angeles. When he is sentenced to death for a crime that he did not commit, he pleads exile in a last-ditch effort to save his life. He is sent out into the unknown with nothing more than a HAZMAT suit and a small supply of food and water.

Believing that he will die in a world made lifeless by war, he is surprised to find that life still survives on the surface as if it were thousands of years agoliterally. Knights on horseback keep order, while peasants work for the lords who, in turn, serve the all powerful king. When they said nuclear war would send us back to the Dark Ages, they were not kidding. How will Jensen survive this strange new world, and will he live long enough to find justice?
