Morgan Freeman is stepping behind bars and bringing to life the most incredible real-life prison breaks.

"Supermax" prisons are supposed to be inescapable fortresses, designed to keep the worst of the worst safely locked away. But it's amazing what ingenious convicts are capable of pulling off.

The Battle of Alcatraz tells the story of one of the greatest jailbreaks of all time. The year is 1946, and five desperate convicts launch a brilliant escape plan. That is, until mayhem erupts, and the Rock becomes the site of a dramatic and violent stand-off.
