A coup d'etat happens in the kingdom of Forland, resulting in the death of the King. In his final hours, the King sends his second child, Princess Alita Forland, to flee. Unfortunately, a life-or-death scenario between Alita and the violent bounty hunter Falis compels the two of them to exchange bodies while fleeing. Alita, desperate for her Kingdom's protection, asks Falis to return and safeguard it, giving herself as collateral. Falis reclaims the title of Princess of Forland after a fast defeat of the rebel troops, giving birth to the most vicious princess in their land, the "Murder Princess."
