Sunset Shimmer was never about making friends. She always thought first of her studies with Princess Luna. When she is sent to Ponyville to check out preparations for the Winter Moon Festival, it doesn't happen as she expected. Daybreaker escapes her prison in the sun and Sunset Shimmer, along with the mares she has met, must work together to prevent Daybreaker from causing eternal day.

Thanks for red reaper for the help
