Racecar Lightning McQueen (Owen Wilson) and his tow-truck buddy, Mater (Larry the Cable Guy), have had their share of adventures together, but nothing like what they experienced when they headed overseas for the first-ever World Grand Prix. While Lightning has his eye on the road to the championship, Mater detours from international espionage when he meets British master spy Finn McMissile (Michael Caine) and stunning spy-in-training Holley Shiftwell (Emily Mortimer).
