Queen Chrysalis, disguised as Princess Cadence, is hard at work preparing for the invasion of Canterlot. Over the last few days, she's been carefully milking Shining Armor, captain of the guard, for all the information on the capital's defenses she can get her hooves on.

But one such defense leaves her confused and curious. A brief conversation with Shining later finds the changeling queen trapped, terrified, and in for the wildest ride of her life.
