Sunset Shimmer is a master thief who uses clever tricks to steal with her partner, Starlight Glimmer. After discovering that the money they robbed from a casino is counterfeit, they go to the country of Everfree, which is rumored to be the source of the forgery. But, when they enter the country, Sunset Shimmer comes across her ex-boyfriend, Prince Rough Draft, who is being forced to marry the ruler of the country, Queen Adagio Dazzle. With the help of Starlight Glimmer, and a samurai named Tempest Shadow, Sunset Shimmer goes on a heist to rescue the love of her life while trying to find out the queen's sinister plot. Will she stop Queen Adagio Dazzle and save the prince, or will she be captured by her longtime enemy, Inspector Twilight Sparkle?
