An American factory worker, a French journalist and a London school boy set out on a spiritual journey after death touches their lives in different ways.

Since winning the Wings Around the Globe race in the Planes (film), Dusty Crophopper has had a successful career as a racer. Unfortunately, his engine's Transmission (mechanics) becomes damaged because Dusty routinely operates the engine beyond its design limits. With that particular model of gearbox now out of production and none available anywhere, Dusty's mechanic Dottie fits a warning light to his control panel to ensure he doesn't damage his gearbox any further. No longer able to race and faced with the possibility of returning to his old job as a crop-duster, Dusty goes on a defiant flight and tests his limits. In doing so, Dusty exceeds his limits and makes a forced landing at Propwash Junction airport, causing a fire.
