The Wonderbolts are putting on a show in Manehattan and Rainbow Dash just has to be there. But arriving a day early means that she and her friends, Pinkie Pie and Fluttershy, have twenty-four hours to whittle away. And what better place to kill time than the mall? In the largest shopping center in Equestria they'll find food, fun, maybe even a new friend. A whole day of hi-jinx and shenanigans.

But unbeknownst to the three friends, something is being hidden within the walls of Manehattan Mall. A dark secret hidden from the masses. And they're about to get involved, whether they like it not.
