Sunset Shimmer and Sunset Demon have been fighting as the Magical Warriors Shimmering Love and Fire Beauty for the past few months. However, the demon forms of Snips and Snails used magic to force Sunset Demon to become evil again and quit becoming a Magical Warrior so she can help the Demon King take over the human world. One night, Sunset Shimmer has a sleepover with her friends, and later that night, is visited by Sunset Demon, who leads her to an alternate universe. In this alternate universe, Sunset notices that there are only two humans living there: Mystery Mint and Sunrise Shine, a young girl who reminds Sunset of herself. She also meets that universe's versions of the demon versions of Snips and Snails. She makes new friends with the girls and the demons, but she soon notices that the universe she went to is not safe for her. Will she be able to return back to the human world, make Sunset Demon nice again, and save the human world from the Demon King?
