In the 23rd century, what remains of society is sheltered inside a high-tech domed city. Shades of the Brave New World, poverty, sickness, and war have been eradicated in this futuristic utopia. Babies are grown inside test tubes rather than born. With every needs taken care by the city's central computer, humanity devotes itself to pleasures and games. The catch: no one lives beyond the age of 30. Those who reach 30 must participate in carousel to "renew" their souls into the next generation of newborns. Those who reject this path are brutally hunted down by sandmen, the city's enforcers. For Logan, that fateful day has arrived. The former sandman has decided to run and find the mythical "sanctuary".
