Alcatraz, "The Rock", has just re-opened. The first criminal to go to the electric chair is also sitting on a secret worth $200 million. An invading group of commandos isn't about to let that fortune go up in smoke. Already having an undercover FBI agent in Alcatraz, the situation has to be neutralized and he has to rescue a Supreme Court Justice held hostage. Now, he has to convince his convict "partner" and the other inmates to fight on the right side of the law.
