Ever since Cinderella left those horrid stepsisters of her's, (not to mention their nasty mother), she and Prince Charming have indeed lived happily ever after in their beautiful castle. But now that she is more content than her stepsisters ever will be, Cinderella feels sorry for them. "I want them to be as happy as I am," she tells her Prince one night. "If only they had a husband as nice as you! I know ... let's throw a grand party for them! That would surely cheer them up, and they could make some new friends." But nothing goes as planned. Despite their kind attempt, Cinderella and Prince Charming are about to learn that if someone has made up her mind to be spiteful and miserable, nothing in the world can make her happy.
