In 1992 Ray Krone, a former sergeant in the US Air Force, was sentenced to death for the murder of Kimberly Ancona, a bar manager found stabbed to death in a restaurant near his home in Arizona. There were countless holes in the prosecution's case and ten years later the victim's clothes were examined using newly-developed DNA testing technology. Krone was completely exonerated and released from jail, but not before he'd spent an entire decade on death row. DEAD MEN WALKING tells the incredible stories of those men and women who have lived their lives behind bars with the constant threat of death by fellow prisoners, or by state execution, hanging over them. What is it like to live out your days inside one of the world's toughest prisons, knowing you'll never again see beyond the exercise yard? Is it really possible to make friends, or form relationships inside? What should you do if, like Ray Krone, you've been sentenced to die for a crime you did not commit?
