In Ponyville, there is a group of six friends whom every resident knows. Rainbow Dash, weather captain and skilled athlete. Pinkie Pie, apprentice baker and town party specialist. Rarity, the fashionable fashion-designer. Fluttershy, the introversive animal caretaker. Applejack, the co-heir of the famous Apple Family Acres apple farm. And Twilight Sparkle, a bookworm who rose to be one of the four Princesses of the realm.

Still, everypony has their secrets, and these six mares are no exception. Each of them has a past that no one in Ponyville has heard; that they keep even from their closest friends. For some, scars have followed them into the present. Others have tried to leave their pasts behind them. And a few only have pieces of the story themselves.

But secrets don’t last forever. When Fluttershy vanishes from Ponyville, the subsequent search will force each of these friends to face the consequences of their long-hidden pasts.
