The true story of three inmates who attempt a daring escape from the infamous prison, Alcatraz Island. Although no one had managed to escape before, bank robber Frank Morris (Clint Eastwood) masterminded this elaborately detailed, and, as far as anyone knows, ultimately successful, escape. In twenty-nine years, this seemingly impenetrable federal penitentiary, which housed Al Capone and "Birdman" Robert Stroud, was only broken once by three inmates who were never heard of again.
