Speed (1994)

A young cop must save the passengers of a bus that has a bomb set to explode if the bus goes below 50 MPH. Bomber terrorist's elevator plan backfires, so he rigs a bomb to a LA city bus. The stipulation is: once armed, the bus must stay above 50 mph to keep from exploding. Also if LAPD Officer tries to unload any passengers off, Payne will detonate it. Joe Morton co-stars as Jack's superior, and Jeff Daniels supports Jack helping him try to defuse the bomb.
