After a long day of racing practice, Mater convinces Lightning McQueen to come along as Mater sneaks up on sleeping tractors, blow his horn and tip the tractors. After causing trouble and allowing the tractors to escape, Mater finds a way to fix all the problems he has caused.

"Did you know that Mater was once the famous bulldozer fighter known as El Materdor? Or that he performed daredevil stunts as Mater the Greater? Or that he was the brave hero of a rescue-squad unit?"--p. [4] of cover.

Sound the alarm and get ready to roll with Lightning McQueen and the firefighters of Radiator Springs!
