In a fairytale kingdom, the king and queen always have a son named Peter, who grows up and ventures forth to rescue a princess from the forces of evil, making her the new queen, etc. However, this cycle is broken one year when the stork delivers a baby girl, Petronella. Tired of waiting for a prince to appear, she decides to venture forth and find one for herself. What she finds turns out to be a lazy good-for-nothing, but still she tries to win his heart by impressing him with her bravery. Successfully completing 3 tasks set by the local warlock, she gets to come away with the prince; but the warlock turns into a dragon and pursues them.
