In the aftermath of the Mare-do-well incident Rainbow Dash has dissappeared from Ponyville and only Twilight and the other Elements may have a clue of where she went, but they aren't talking.

Meanwhile, Rainbow Dash is in for the race of her life when she goes up against the fastest thing alive...Sonic the Hedgehog on the orders of Dr. Eggman/Robotnik.
