Due to an unhappy curse, King Sextimus is unable to speak. Meanwhile, his terror of a wife, Queen Aggravain, has taken over control of the kingdom. Most importantly, in an attempt to keep Prince Dauntless single, she has decreed that only the princess that can pass her test may marry her son. Further, no one else in the kingdom may marry until Prince Dautless does. Lady Larken and Sir Harry are extremely disturbed by this fact since Lady Larking is now pregnant with Sir Harry's baby. Luckily, Sir Harry is able to find an amazing princess, Winifred the Woebegone. She instantly catches the attention of Prince Dautless, and in the end, is able to pass the Queen's supposedly impassable sensitivity test. When the Queen still tries to prevent Prince Dauntless from Marrying, he tells her to 'shut up' which ends up breaking the curse on the King.
Now able to speak, King Sextimus regains his rightful position as leader of the kingdom, and all is well.
