America's most famous prison, Alcatraz is considered an impenetrable fortress. A group of prisoners are tired of living under the firm wrist of the director and his sadistic guards and formulate an escape plan. On May 2, 1946, their freedom struggle begins when they take several guards hostage and attempt to flee the institution. Before long, they are facing not only the director's officers, but a military team led by a tough general. This is the real story of the Battle of Alcatraz, a fight to the death that only the most brutal and cunning will survive.
