Set in a 80's version of Equestria, Rainbow Dash is the head of the Fyre Flys gang in downtown Ponyville. They consist of Gilda, the Muscle, Fluttershy, the Stare master, Pinkie, the Mad Prankster, and Dash, Fastest pony in the city. They work to clean the city up, fighting with rival gangs and general baddies, but aren't looked upon as actually helping. This causes them to want to fight bigger game, and go after known larger crime groups. With the help of Twilight, the Genius Inventor, and Rarity, The Ex-Spy, the gang gets in way over their head, and now they must find out why the gem they hold is so very outrageous, and why everyone wants a piece of the Fyre Flys.
