Under Siege 2: Dark Territory is a 1995 American action film set on board a train traveling through the Rocky Mountains from Denver to Los Angeles. Directed by Geoff Murphy, it stars Steven Seagal as the ex-Navy SEAL, Casey Ryback, and is the sequel to the 1992 film Under Siege also starring Seagal. The film's cast also included Eric Bogosian, Everett McGill, Morris Chestnut, Peter Greene, Kurtwood Smith and Katherine Heigl. Nick Mancuso, Andy Romano, and Dale Dye were the only other cast members besides Seagal to reprise their roles from the first film. Casey Ryback has retired from the United States Navy and is a chef at the Mile High Cafe in Denver, Colorado. Casey is taking his estranged niece Sarah to Los Angeles to visit the grave of Sarah's father. Sarah and Casey board the Grand Continental, a train traveling from Denver to Los Angeles through the Rocky Mountains. Armed mercenaries, led by former U.S. government computer hacker and computer genius Travis Dane and mercenary leader Marcus Penn, hijack the train. Dane worked on Grazer One, a top-secret military satellite particle weapon designed to destroy underground targets. The military fired Dane because of his mental instability; Dane later faked his suicide. The mercenaries take the train's passengers and staff hostage, herding them into the last two cars.
