Lightning McQueen and Mater were enjoying a good race around the Radiator Springs that lasted into the evening when they drifted around the canyon to see a bizarre cavern that clearly wasn't present beforehand, with the cars noticing that it was brightly glowing that in turn contrasted with the sunset.

"Uhh was that there when we last passed by here?" Mater asked.

Lightning squinted his eyes. "You know I don't recall... it wasn't present when I went drifting around here for practice."

"Maybe it's from the future!" Mater laughed while spinning his hook around. "Time for me to see what's inside!"

"Oh Mater wait-" Lightning called out for he followed the tow trick, with both of the vehicles suddenly being sucked inside for the cavern suddenly collapsed on itself into the sand.

Lightning and Mater screamed upon finding themselves in a weird rainbow vortex, only for them to suddenly be released into a race track filled with various racers, confusing them for they were forced to simply drive as if they were part of this new race.
