When a nasty bout of feather flu renders Fluttershy unable to model for Rarity at an important competition in Canterlot, she is forced to turn to another one of her friends at the last minute in order to find a replacement. Unfortunately, the replacement comes with a few ... issues of their own. Will the show be a rousing success and another feather in Rarity's cap or will Applejack's lack of refinement lead to strife between the two?
