Under Siege 2 PILF-2177 ( 0183 )

Following his retirement from the United States Navy, Casey Ryback settles in Denver, where he runs a restaurant. When he receives news of the death of his estranged brother, James Ryback, in a plane crash, Casey meets James's daughter, Sarah, whom he will accompany to Los Angeles to attend his funeral. The two board the Grand Continental, a train traveling through the Rocky Mountains from Denver to Los Angeles. On board, they befriend a steward/porter named Bobby Zachs and the train's chefs.

As the train reaches the Rocky Mountains, a group of terrorists flag it down and murder the engineer and brakeman. The group, led by former U.S. government employee and computer genius Travis Dane and Marcus Penn, cut the train phone lines and take the passengers and staff hostage, herding them into the last two cars. Casey kills one terrorist, then slips away. For underground targets, Dane worked on Grazer One, a top-secret military satellite tectonic weapon. The military fired Dane, who later faked his suicide.

Dane threatens two former Department of Defense colleagues with burning soldering irons in their eyes unless they reveal codes to take over Grazer. Despite their disclosures, they are thrown from the train over a deep valley after the codes are confirmed to work.

Middle Eastern terrorists have offered Dane $1 billion to destroy the Eastern seaboard by using Grazer to target a nuclear reactor located under the Pentagon. Dane demonstrates Grazer to investors by destroying a Chinese biological weapons facility that was passing itself off as a fertilizer production plant. After one investor offers an additional $100 million, despite the weapon's primary intention for subterranean targets, Dane destroys an airliner carrying the investor's ex-wife.

The U.S. government has difficulty locating Dane or Grazer. When officials destroy what they think is Grazer, Dane explains the NSA's best intelligence satellite was destroyed. His location cannot be determined as long as the train keeps moving.

With Zachs' help, Casey takes matters into his own hands. He faxes a message to his restaurant, which relays it to Admiral Bates. Bates quickly understands that Dane and the terrorists are on the train and reluctantly approves a mission by two F-117 stealth aircraft to destroy the train.

Zachs discovers they are on the wrong tracks and on a collision course with a Southern Pacific bulk freight train carrying gasoline tank cars. Casey kills the mercenaries one by one and releases the hostages, but Dane uses his computer skills to find the F-117s and then re-target Grazer to knock them out before they complete their mission. Aware of Casey's past, Penn uses Sarah as bait to lure him to a fight, but Casey gains the upper hand and fatally breaks his neck.

Ryback finds Dane about to depart in a helicopter hovering over the train. When Dane informs Casey that there is no way to stop the satellite from destroying Washington, Casey shoots him. The bullet destroys his computer and injures Dane, who falls out of the window of the train. Control of the satellite is restored at the Pentagon and destroyed by remote control one second before it would have fired on the Pentagon, just before the two trains collide.

The crash happens on a trestle, resulting in an explosion that destroys the bridge and kills Scotty, the mercenary driving the train. Ryback races through the exploding train, exits the carriage, and grabs a rope ladder hanging from the helicopter. Dane, who survived the gunshot and the crash, also catches onto the ladder. He hangs onto the helicopter, begging Casey to save him, but Casey shuts the door, severing Dane's fingers and sending a screaming Dane falling to his death.

Casey informs the Pentagon that the passengers are safe, having previously detached the last two cars from the rest of the train. Later on in Los Angeles, Sarah and Casey pay their final respects at James' gravestone.
