This story is a sequel to Chasing Thieves
Tirek, an international criminal mastermind with eyes in every corner of the globe, has secured two halves of a treasure that is said to lead to a land rich with magic - the land of Equestria. He still needs two more items, though, before the portal can be opened.
FBI agents Shining Armor, Chrysalis, Cadance, Blueblood and Gilda, together with Equestrian native Sunset Shimmer, must find these items before Tirek's people do. Enlisting the help of former villains familiar with Equestrian magic and archaelogical expert Daring Do, the race is on to save Equestria.
