Sixteen-year-old Rasheed is smart, tough and a survivor. In his neighborhood, he has to be. The streets are run by a gang called the E Street Locals, and they've been trying to jump him in since he was a child. So far, he's managed to escape their clutches. But the gang is not his only problem. Rasheed's sister, Daneeka, was paralyzed in a drive-by shooting, and now she's confined to a wheelchair, mentally frozen at the age of nine. His mother is an addict. His father hasn't been heard from in years.
The year is 2147. Chago, twenty-four, is a prisoner in a world made up only of prisoners and those who guard them. The only bright spot in Chago's life is his son, Jim-Jim, whose mother is a guard. In an effort to resolve overcrowding in the prison, the warden introduces the Innocence Device, a high-tech machine he claims can determine innocence or guilt. Prisoners are encouraged to walk through the Innocence Device and experience its rewards: immediate freedom or death. When they discover the machine is rigged, the prisoners riot and take over the prison.
