Output: A group of rogue U.S. Force Recon Marines, led by disenchanted Brigadier General Frank Hummel and his secondincommand Major Tom Baxter, storm a heavily guarded naval weapons depot and steal a stockpile of deadly VX gas–armed M55 rockets. The next day, Hummel and his men, along with Marine Captains Frye and Darrow, seize control of Alcatraz Island, taking eightyone tourists hostage. He threatens to launch the rockets against San Francisco unless the U.S. government pays him 100 million from a military slush fund, which he will distribute to his men and the families of Recon Marines who died on clandestine missions under his command but whose deaths were not compensated. The Pentagon and FBI develop a plan to retake the island with a U.S. Navy SEAL team led by Commander Anderson, enlisting the FBIs top chemical weapons specialist, Dr. Stanley Goodspeed. FBI Director James Womack is forced to offer a pardon to federal prisoner John Mason, in return for information. Mason, a 60yearold British national imprisoned without charges for three decades, is the only Alcatraz inmate to ever escape the island. After being setup in a hotel, Mason escapes, resulting in a car chase with Goodspeed through the streets of San Francisco. While seeking out his estranged daughter, Jade, Goodspeed arrives, but covers for Mason by telling Jade that he is aiding the FBI. Goodspeed, Mason, and the SEALs infiltrate Alcatraz but Hummels men are alerted to their presence and ambush them in a shower room. All the SEALs are killed, leaving only Mason and Goodspeed alive. Mason sees his chance to escape custody and disarms Goodspeed, but is convinced to help Goodspeed defuse the rockets after the Marines use explosive devices to flush them out. They eliminate several teams of Marines and disable 12 of the 15 rockets by removing their guidance chips. Hummel threatens to execute a hostage if they dont surrender and return the guidance chips; instead, Mason destroys the chips and surrenders to Hummel to try and reason with him as well as buy Goodspeed some time. Though Goodspeed disables another rocket, the Marines capture him. With the incursion team lost, the military initiates their backup plan: an airstrike by FA18s with thermite plasma, which will neutralize the poison gas but kill everyone on the island. Mason and Goodspeed escape, and Mason explains why he was held prisoner: he was a British SAS Captain who stole a microfilm containing details of the United States most closely guarded secrets, refusing to give it up when captured because he knew he would be killed if he did. When the deadline for the transfer of the ransom passes, Hummel fires one of the rockets, but then redirects it to detonate at sea. He reveals to the Marines that the mission is over and that it was all an elaborate bluff as he never had any intention of taking innocent lives. Hummel orders them to exit Alcatraz with a few hostages and the remaining rocket to cover their retreat while he assumes blame. Frye and Darrow rebel upon realizing they will not be paid their 1 million apiece, killing Baxter and mortally wounding Hummel, who tells Goodspeed where the last rocket is before dying. Darrow and Frye proceed with the plan to fire on San Francisco. Goodspeed seeks out the rocket while Mason deals with the remaining Marines. As the jets approach, Goodspeed disables the rocket before killing both Frye and Darrow. He signals that the threat is over just as one jet drops a bomb; though no hostages are injured, Goodspeed is thrown into the sea by the blast and Mason rescues him. Goodspeed and Mason part ways after Mason reveals the location of the microfilm; Goodspeed fakes Masons death by telling Womack that he was killed in the bomb explosion. Sometime later, Goodspeed and his newlywed wife Carla are seen stealing the microfilm from a church and driving away.
