Brady (Mitchel Musso) and Boomer (Doc Shaw) are twin teens. After being bullied by the toughest guys in the school, Mason (Geno Segers) and a group of warriors from their kingdom in Kinkow come to bring them home. They break the sacred ruby and the volcano on the island erupts. Lanny (Ryan Ochoa) tricks them into going to get another sacred ruby so they would die in the dark side of Kinkow, but Brady and Boomer were able to get the sister ruby, and save the kingdom.
