Twilight Sparkle is planning her Friendship Festival, and everything has to be perfect. She asks the other princesses to help her so that the sun and moon are right in the sky so that the weather is as beautiful as possible. But suddenly the storm clouds gather over Canterlot. The thunderstorm begins to rumble and the ponies start to get really scared. A mysterious airship is approaching, threatening to destroy both the Friendship Festival and the whole of Equestria.
We also meet the little foal Flurry Heart, who does not want to sleep even though Princess Luna has set the moon in the sky. Flurry Hearts mom and dad, Princess Candace and Shining Armor do everything they can to get their little foal to sleep.
