It started out as an ordinary day for Fluttershy – waking up in her house in Cloudsdale and going to work managing the weather for Ponyville alongside her best friend Cloud Kicker. However, she finds herself troubled by feelings she can't explain, feelings that something serious is wrong. When she starts having visions of a strange life with strange ponies, she's determined to find them and find out what's going on. But how can such a timid pony convince others of what she isn't sure of herself?

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!
