The film tells the story of the LAPD cop who tries to rescue civilians on a city bus rigged with a bomb programmed to explode if the bus slows down or if civilians try to escape.
Los Angeles SWAT officers Jack Traven and Harry Temple thwart an attempt by a bomber to hold an elevator full of people for amillion ransom. They corner the bomber, but he grabs Harry. Jack shoots Harry in the leg, forcing the bomber to release him. He turns and runs around a corner, apparently dying in an explosion. Jack and Harry are praised by their superior, Lieutenant Mac McMahon.Later, Jack sees a city bus explode. The bomber then contacts him, explaining that a similar bomb is rigged on another bus, and will get activated if it goes over 50 miles per hour 80kmh and blow up when the speed drops below 50. The bomber demands a larger ransom of 3.7 million and says he will set off the bomb if any passengers are offloaded. Jack races through traffic and manages to board the moving bus, but by the time he gets on board, it is already going over 50 and the bomb is armed. Jack explains the situation to the driver, Sam, but a panicked smalltime criminal on the bus, fearing Jack is going to arrest him, fires his gun, wounding Sam. Another passenger, Annie Porter, takes Sams place behind the wheel while Jack explains the situation to everyone aboard. Jack examines the bomb under the bus and phones Harry, who uses clues to identify the bomber as a former police officer. ........
