The Elements of Harmony have finally defeated Discord and brought peace back to Equestria. Everything's back to normal, but one of the Elements, Rainbow Dash, feels disappointed about how quickly her adventure ended and pondered on what it would be like to go on adventures with her hero, Daring Do. As Daring Do, who is a book writer in Canterlot, read about Rainbow Dash's feats in the news, she also began to wonder what it would be like to go on adventures with someone as strong and loyal as Rainbow Dash as her sidekick. They both see a shooting star fly in the sky, make a wish and suddenly depart on an unexpected journey far, far away from Equestria. In addition, the wish they made was only granted part-way. With Rainbow Dash as the sidekick of a well-know adventurer of Capital Wasteland and Daring Do being protected by said adventurer's "manservant", the two parties venture onto two different adventures in the post-apocalyptic Washington. How will they fare and, more importantly, does either one of them know that they're both closer to eachother than they think?
