A well-intentioned, but bumbling security guard at the Museum of Natural History is taken on the adventure of a lifetime when an ancient curse brings to life all of the artifacts in the museum and threaten to wreak havoc in the city.

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.
