Retired police officer Payne killed the patrolling police, planted a bomb in the elevator, and demanded a million ransom for 13 hostages. SWAT Jack and Harold wit and courageously removed the bomb and rescued the hostages at the very moment. But Payne was able to escape. Jack and Harold were commended for this action, but Payne retaliated. He blew up a bus and called Jack to tell Jack that he had installed a time bomb in another bus. As long as the speed of the car exceeds 50 miles per hour, it cannot slow down, otherwise it will cause an explosion.
Jack drove up to the bus and tried to get on the bus. But at this time the speed has exceeded 50 miles per hour. The driver was shot and injured in the chaos, and passenger Annie became the driver. They experienced thrilling traffic jams and roadless conditions along the way, but finally did not slow down and moved to a highway that has not yet been activated. In the police station, Harold found Payne's address and went to arrest, but was killed in the bombing, and Payne asked for the ransom as soon as possible. As the time limit for paying the ransom is getting closer, Jack wants to take the risk of dismantling the bomb, but not only fails, but accidentally finds that the car is equipped with a monitor. When McMahon learned about it, he took the plan and asked the news car to intercept the signal and replay the fake images continuously in order to gain the opportunity to divert passengers. But at this time Jack used a parallel shuttle bus at the airport to safely transfer all the passengers. In the end, the bomb-mounted bus hit an obsolete Boeing 707 passenger plane and exploded.
Payne took the ransom money under the siege of the police and kidnapped Annie. When Jack catches up with Payne, he finds Annie is in his hands and his whole body is full of explosives. Payne escaped into the subway and killed the driver. On the roof of the car, Jack and Payne had a life-and-death struggle and eventually defeated Payne. Jack finally rescued Annie, but the subway was out of control. Jack was anxious and stunned. He drove the subway out of the track using a curve, rushed out of the ground and stopped. Jack and Annie finally escaped the clutches of death again.
After a series of life and death experiences, Jack and Annie are already dependent on each other. The two kissed and kissed each other.
