Lightning McQueen and Mater are driving in Radiator Springs and drive past Red, who is hosing some plants near Stanley. Mater tells Lightning that he used to be a firetruck, but Lightning doesn't believe Mater.
The film then shows a burning building (the gasoline and match factory) and many cars are scared. Mater is then shown as a firetruck and the fire alarm rings. Mater quickly zooms over to the burning building and shoots water at the burning building. Tia and Mia are there, too and are painted white with black spots like Dalmatians.
Then, the film goes back to Lightning McQueen and Mater. Lightning tells Mater that he doesn't believe him about being a firetruck. Mater tells McQueen to remember that "you was there, too".
The film then goes back to Rescue Squad Mater rescuing Lightning from the building and put into an ambulance just when the building blows up. Lightning is then rushed to the hospital and seen going though many doors and then seen in Dr. Mater's office revealing that Mater is a doctor too. Tia, Mia and Kori Turbowitz also appear as nurses, along with a yellow GTO. Lightning is then seen screaming as he is getting repaired.
Back in Radiator Springs, Lightning argues and says that it didn't happen, but when the yellow nurse drives by, Mater says, "Did, too." and drives away, and the short ends.
