PSP Movies - L.A. bomb squad experts Jack Traven (Keeau Reeves) and Harry Temple (Jeff Daniels) have just foiled a mad bomber's plot by saving a group of hostages trapped in the elevator of an L.A. skyscraper. Traven, however, lets the bomber, Howard Payne (Dennis Hopper), escape. Payne sets out for revenge, blowing up a packed city bus right before Traven's eyes. Traven answers a nearby payphone, only to learn that Payne's planted another bomb on another bus. Once the bus hits 50 mph, the bomb will be engaged. And when the bus' speed drops below 50, the bomb will explode, killing everyone onboard. It's up to Traven and Temple to find the bus and outwit Payne before it's too late. The action, like the bus, just can't slow down.
