Twilight Sparkle receives a letter from Princess Celestia. As a reward for her and her friends diligence in sending friendship reports, they will be treated with a trip to Manehattan to see a show. On their way to the 'city that never sleeps', Twilight senses that something is going on behind the scenes, a lingering trace of familiar magic is in the air, one that she feels is connected to everything. One thing is for sure. This isn't a simple vacation.
