Lightning McQueen is a cocky, rookie race car. Speeding on his way to a big race, he crashes into Radiator Springs, destroying lots of the inhabitants belongings. In order to make up for what he did, the cocky roadster is sentenced to community service. Though he will do anything to get away from the work, McQueen must learn to respect and bond with the Radiator Springs inhabitants in order to get out of the town and back on the racetracks.
My son has watched this endless times. He loves the interaction between the characters of Lightning McQeen and Mater as they make him laugh.
