Indomitable in his desire to win always and everywhere, a race car "Lightning" McQueen discovers that has gone astray and is stuck in a small provincial town of Radiator Springs, which is located somewhere on Route 66 in California. Participating in the race for the Piston Cup, where he confronted two very experienced opponents, McQueen did not expect that from now on he would have to deal with the characters of a different kind. This, for example, is Sally - a chic Porsche model of the year 2002, Doc Hudson - a "Hudson Hornet" passenger car of 1951, or Meter - a rusty truck-tow. And they all help McQueen to understand that in the world there are more important things than fame, prizes and sponsors.
