In a distant kingdom live six mysterious princesses, each with a particular power. One of them, in an ever-changing mood, rules time and natural disasters, but hides a terrible secret: whenever the children of the world are angry or crying, they lose control and become a threatening fire-breathing dragon. The five sisters then spoke to try to placate it. When the princess comes to her senses, the world finally finds its harmony ... provided, of course, that all the children are good and kind!
