The sole purpose of Alcatraz was to degrade, deprive, humiliate and break the inmates physically, mentally and spiritually, if possible. In many cases it was remarkably successful. The most notorious federal penitentiary in the history of America knows many personal stories. Following the life of an inmate, we'll meet his buddies - Al Capone and Machine Gun Kelly- and some other illustrious characters. A few of them try to escape, but NO ONE escapes from Alcatraz!
