In the U.S., there are approximately 100,000 inmates held in supermax prisons and isolation units, confined in 8 feet by 10 feet windowless holes for 23–24 hours a day. Terry Allen Kupers, one of the world's leading experts on the effects of solitary confinement, takes us inside the minds of some of the thousands of inmates in these cells. He provides constructive rehabilitation alternatives for solitary confinement.

Kupers is an award-winning psychiatrist and a professor emeritus. As one of the nation's foremost experts on the mental health effects of solitary confinement, he has testified in over two dozen action lawsuits about jail and prison conditions.
