Olivia Embers has been waiting for this her whole life.
The Piston Cup championship.
For years, all she's ever dreamed of was winning - to be the youngest female racer to succeed in scoring the trophy. She's dedicated everything to make it possible, and she's trained with the best. It doesn't help that her rival, Lightning McQueen, appears to charm his way into her life all so suddenly, or that her sister Sally is making her life a living hell.
For her, it's just out of reach as the last race ends in a four-way tie. And just after, a scary event turns the tide, one that could possibly end her career. Now, she returns to her home, Radiator Springs, with Lightning McQueen in tow. Serious tensions arise between the multitude of people in the small town, and with the race being rescheduled, will Olivia be able to make her mark, or will her efforts not be enough?
After several months of racing, Lightning McQueen and Doc are looking forward to some rest and relaxation in Radiator Springs. Needless to say, they don't get it.
Behind everyone's backs, a billionaire scientist has been working on a project that inadvertently brings six humans (Nikki, Zane, Hector, Elsie, Zhara, and Abbey) into the car world. If they want to get home, they're going to need the help of everyone in Radiator Springs. It doesn't help that the billionaire who brought them there in the first place is looking for them...and willing to do whatever it takes to get them back.
