After a sudden coup d'etat by the court scientist Dr. Akamashi results in the king's death, Princess Alita Castilia Arago Forland is forced to flee the capital. During her mad dash for survival deep into the forest, Alita collides with the brutal and temperamental bounty hunter Falis, which causes the two women to magically switch bodies. Using her original body as collateral, Alita convinces Falis—and her henchmen Dominikov and Pete—to help take back the capital from the treasonous scientist by pretending to be the real princess. However, while the plan was initially successful, the only diplomacy Falis knows is with her sword. Alita must now work hard to make sure the kingdom is not trading one royal scandal for another, all while the two displaced women look for a way to return to their original bodies.
