The princess (now named Althea) loses her gravity and the ability to cry at age six, after her mother dies. Her father became a cold-hearted man after the loss of his wife. Their country Lagobel (which is rich in gold, but has no water) is at war with the neighboring Sealand (which has water, but no gold). When Althea's older brother is killed her father tells her she must prepare to be queen, but she laughs and refuses, leading to a disheartened Lagobel army being slaughtered in battle with Sealand troops. Althea's father tries various cruel cures to find her gravity, and tries to force her into an arranged marriage so she can provide a child to be a more suitable future monarch, but she escapes and flees to the wilderness that separates Lagobel and Sealand. There she meets Sealand's prince, Digby, who has been unable to smile since the death of his mother. The two fall in love and conceive a child, but soon fight as Digby wants a more traditional life in a house, while Althea wants to live in the lake forever. Digby returns home, where his cruel father dams the lake in order to cut off Lagobel's water supply and kill all the people. Digby runs away from his own arranged marriage and breaks down the dam, but is nearly killed in the process, causing Althea to cry and therefore regain her gravity. The two get married and live happily ever after, Althea becoming a marine biologist and leaving the running of the country to her female prime minister.
