Eleven-year-old Luke longs for an adventure to escape being sick in the hospital. As a medieval princess and her dragon come to life from his jigsaw puzzle, he doesn't know what to believe. When she grants him and his little brother, Peter, a wish in exchange for help, they can't afford to say no.
Peter would do anything to help his brother get better, including traveling to another world on a quest and recruiting their best friends, Mark and Rose. With time running out, they battle against evil not knowing if their wish will be granted. Any adventure has risks and a wish can have unwanted consequences. But when it comes to fighting for the ones they love, nothing will get in their way.
