Crown Prince Ferdinand's fiancée, the Duchess's daughter Margaret Lewis, has been poisoned and fallen ill. Ferdinand, seeing his unconscious fiancée, gets serious and corners the culprit. Moreover, he tackles the country's problems one after another. Or so it seems, but he is actually just being manipulated by Margaret, who has undergone an out-of-body experience.
