Hijack

When a high-profile Senator (played by Ernie Hudson of GHOSTBUSTERS fame) boards a train at Union Station, he is expected a typical, smooth ride. However, his trip is violently interrupted when a militia group hijacks the train, taking him and several other passengers as hostages and planting a nuclear bomb somewhere on board. An intrepid ATF Agent (THE LAWNMOWER MAN's Jeff Fahey) who happens to be a passenger on the train is the one man who just may be capable of both freeing the hostages and defusing the bomb before time runs out.
