A renegade general and his crack team of mercenaries take over the abandoned fortress prison of Alcatraz and threaten San Francisco with toxic nerve-gas rockets to extort a massive ransom. To break their stranglehold on the city, the FBI pairs a chemical weapons expert and a jailed SAS veteran, chosen because he is the only man to have ever escaped from the infamous penitentiary. Action thriller, with Sean Connery, Nicolas Cage and Ed Harris.

When vengeful General Francis X. Hummel seizes control of Alcatraz Island and threatens to launch missiles loaded with deadly chemical weapons into San Francisco, only a young FBI chemical weapons expert and notorious Federal prisoner have the skills to penetrate the impregnable island fortress and take him down.
