We all know the fairy tale: a princess gets locked in a tower by a dreadful dragon and is rescued by a fair prince, swept away to go live out her happily ever after with a man she just met. Right? Wrong. The dragon was, in fact, the princess's closest friend. So, when the prince brutally butchers the creature, she is understandably upset. Rather than swoon at his feet or offer him a token of her gratitude, the princess takes up her own sword and swears revenge on the man who took her best friend from her. And nothing will stop her.
