When Canterlot Highschool goes on a trip to Camp Everfree, they’re surprised to find a magical force is causing strange things to happen around camp. With the help of the Mane 6 and especially Sunset Shimmer, Twilight Sparkle must confront the dark “Midnight Sparkle” within herself and embrace her newfound magical abilities to save the camp.
