Lord Tyrone, newly married to Lady Isabella, is accused of stealing the king's statute which was to be used as a proxy for the king's marriage. Lady Isabella, her cousin Katherine, and her swordmistress Florence flee assassins by sailing out to sea on Lady Isabella's pleasure vessel, Katherine, mortally wounded dies. Isabella and Florence land at an Island ruled by a dragon queen. A usurper to the throne, Queen Judymal has Isabella and Florence thrown over a cliff to feed a sea dragon. The two manage to swim to safety to a cave where they find the king's proxy statue. The dragon, Belinda, comes, a shape-shifter in love with king. Belinda stole the proxy statue so that no one else could marry the king. Belinda agrees to return the statue to the king to save Lord Tyrone's life. The king's court has turned on him, but assisted by Belinda, Florence, Lord Tyrone and Isabella, he defeats the traitors. The king joins the others in returning to Belinda's island to win back her throne from Judymal.
