In this 1995 sequel, Casey Ryback (Steven Seagal) is taking a train trip with his niece, Sarah (Katherine Heigl) from Denver to L.A. A criminal mastermind, Travis Dane (Eric Bogosian) hijacks the train in an effort to take control of a military satellite superweapon.
Dane built the weapon but then was fired by the government before it was deployed. He has teamed up with Middle Eastern terrorists who have offered him $1 billion to use the satellite to blow up the Eastern seaboard by targeting a secret nuclear reactor.
Trivia: Filmmakers pioneered a new technique that enabled them to film all the interior train scenes (practically all the film) in the studio. Tennis balls glued on the studio walls were used as reference points to allow computers to insert footage of Colorado scenery, even when the camera moved around.
