Brady and his twin brother Boomer were a pair of teenage fraternal twins raised by their aunt and uncle in Chicago and lived a normal existence. However, when Mason, the royal adviser to the throne of the island of Kinkow, arrived at their high school, they learned that they were the heirs to the throne of the island. After Mason tells Brady and Boomer of their lineage, the brothers relocate to the island of Kinkow to assume their roles as the joint kings of the island nation, which has many odd customs and superstitions.
The oldest twin was supposed to rule alone, but, since all records of which twin Brady or Boomer is the eldest were lost, the two of them must rule together.
