Iron Heights is the toughest penitentiary in Central City—tough enough to hold rogues like Captain Cold and Mirror Master. But lately it’s been a prison of sorts for Barry Allen as well, ever since Barry was pulled off his job as a CSI and sent to the facility to work in crime scene preservation. From his new post, the Fastest Man Alive witnesses for the first time what life is like for criminals after their arrest. And thanks to Iron Heights’ tough-as-nails Warden Wolfe, it isn’t pretty.

 But now life in prison has turned into a death sentence for one inmate, and since Barry’s no longer working at the crime lab, he isn’t able to help the murder investigation. As the Flash, however, he’s determined to get to the bottom of the mystery, even if it runs him headlong into a trap.

 A new player has been giving Copperhead, Central City’s leading crime lord, a run for her money, and whoever it is has ties to the prison...and the murder. Can the Flash solve the mystery and take down a rising crime boss, or is there really no escaping Iron Heights?
