It is time for Sunset Shimmer to move out. An assignment leads her to a new home in Ponyville - but why?

Meanwhile, Luna prepares Canterlot Castle for a possible attack. She doesn't want to banish Daybreaker for another thousand years. She wanted Celestia to be freed from Daybreaker's grip. Just as the sun rises, the banished alicorn escapes the sun.

Will Sunset save Equestria? Or will Daybreaker reign as a terrible tyrant?
