Welcome to Alcatraz. The Rock has just re-opened for business, but the first criminal slated for the electric chair is also sitting on a secret worth $200 million. And an invading group of commandos (led by Morris Chestnut) isn't going to let his fortune go up in smoke. Already undercover in Alcatraz, FBI Agent Petrosevitch (Steven Seagal) has to neutralize the situation and rescue a Supreme Court Justice held hostage. Worse, he has to convince his convict partner (Ja Rule) and the other inmates to fight on the right side of the law.
