General Irwin (Robert Redford) was a POW in Vietnam and a revered hero in the Persian Gulf and Bosnian campaigns. Now, he's been court-martialed for disobeying orders and is sentenced to serve time at The Castle, a maximum-security military prison run by a hard-nosed disciplinarian (James Gandolfini). A battle of wills soon emerges between the two men as the prisoners and guards find themselves drawn to Irwin's natural leadership abilities.
