Rainbow Dash's life couldn't be more perfect. She has awesome friends, a cool pet, and most importantly, a chance at joining THE Wonderbolts, Rainbow's idols and the single greatest flying team in all of Equestria.

Unfortunately for Rainbow Dash, even the fastest flier in Equestria can slip up every once in a while.

When a failed trick causes her to hit her head, she slowly starts to realize her past is a bit different than how she remembered it.

Unsure of how to deal with the flood of new found memories, Rainbow Dash enlists the help of Twilight Sparkle to help uncover the truth and find out why the past that Dash remembers is different than what these new memories reveal to her.
