In a 50's version of humanised Equestria, the Applejack, Pinkie Pie, Rainbow Dash and Rarity struggle through all the difficulties and troubles that life in high school throws at them. Friendships are strained, love blossoms, and two new girls arrive at the school.

It all starts with Rainbow Dash's mysterious crash in the middle of the night. After the dare-devil pegasus is out of the picture, things start happening all over Ponyville. Bad things. No one know's what to expect, or who to blame. All they know is that it's dangerous, and it doesn't look like it's about to stop.
