There's a fuel bandit on the loose in Radiator Springs. Not only does this mean that the cars will soon be running on fumes, but it also makes it impossible for the town's postal trucks to deliver everyone's Christmas letters to Santa Car! Mater's determined to get his letter to Santa, though. Luckily, Fillmore has just enough of his special Christmas gasoline for Mater and Lightning McQueen to make the trek to the North Pole, while the rest of the town investigates the mysterious missing fuel. But when Mater finally meets Santa Car, he learns that Christmas might actually need to be cancelled this year...unless Mater and McQueen can save the day!
