The princess lost her mother and in an attempt to reach for her in the heavens loses her gravity and the ability to cry. Her father has become a cold-hearted man after the loss of his wife and only son Alexander. The princess is called Althea and her country Lagobel becomes at war with the neighboring Sealand. When Althea escapes Dagobel she ends up in 'The Wilderness', a nomansland that separates Lagobel and Sealand. There she meets Sealand's prince, Digby who is unable to smile. The two fall in love, but soon after that they get into a fight about Digby's old-fashioned ideas of marriage and motherhood.
Althea's father undertakes several attempts to regain his daughter's gravity, concluding that love is the cure. He hides her in his dungeon before an arranged marriage, but Althea manages to escape. She flees to the lake that has dried out. Digby decides to break the dam so the water can flow back into the lake. He almost gets killed, causing Althea to cry and she therefore regains her gravity. The two get married and live happily ever after.
