Bullied high school class-clowns and twins BRADY and BOOMER are told they are successors to the throne of a tropical island called Kinkow, and that the time has come for them to begin their rule. But, since it is unknown which of them was born first, they will rule together. Royal guardian and strongman MASON takes them to Kinkow and shows them their castle, where they meet MIKAYLA, Mason's daughter and one of the twins' guides to the many supernatural quirks of the island. The twins at first think that as rulers they will have things easy, but quickly learn the challenges faced by kings are similar to the challenges they faced as bullied high school students back home. For the good of their people, Brady and Boomer must face their fears and learn to become strong, effective leaders. However, their diminutive, scheming cousin, LANNY, wants nothing more than for the kings to perish so he can take the throne.
