Rainbow Dash was probably the most loyal pony in all of Equestria. She was not only a great Wonderbolt, but she was also a great marefriend. When she and Applejack first went on their date she had never looked at Applejack quite the same, and she knew immediately she was the perfect mare for her. Nothing could possibly go wrong for Dash. But when an old enemy from flight camp returns and joins up with an old enemy from Equestria's past, Rainbow Dash will have to face the danger that awaits her. But it's not the danger that scares her, and it's not the fact that all of Equestria might be in her hooves: what scares her the most is losing her marefriend.
