A very different Sunset Shimmer finds herself in a much darker human world. She's found the power she always wanted, but is power what she really needs?
A string of robberies has been going on in Sunset's neighbourhood, but things change when Sunset's apartment is targeted, and the identities of the thieves become a topic of debate amongst her friends.
One drunken night of science and magic has led Sunset and Twilight to create an artifical human named Dawn that recognizes both girls as her mothers. But the magic powering her can only last so long.
Investigating a mysterious pulse of magic when trying to avoid repairing the wedding, Twilight stumbles upon the magic mirror only to get trapped on the otherside. Will a less angry Sunset help her?
