“Unstoppable” is an adventure about a runaway train. When a brake hose snaps loose, a barreling locomotive loses control and becomes a runaway engine of destruction. To make matters worse, the runaway train has containers of toxic waste on board. So now it’s up to two men to stop it; Will (Chris Pine) is a young and upcoming conductor while Frank (Denzel Washington) is an old and tough veteran train engineer. Together the two must catch up with the train before it makes the first bend around a mountain pass that will tip the train, spilling the toxic waste on a unsuspecting town.
