Keanu Reeves stars as an L.A. bomb squad specialist whose principal antagonist is elusive bomber-extortionist Dennis Hopper. Seeking vengeance after his latest ransom scheme is thwarted, Hopper presents a personal challenge to Reeves: a wired-for-destruction city bus, which will detonate if the speedometer drops below 50 mph.
