But things don't go as planned, and she is off on a wild misadventure at sea. She thwarts the lecherous advances of a crazy captain, rallies the sailors to her side, and ultimately gains command of a ship in His Majesty's Royal Navy. But Jacky's adventures don't end there....
Soon she is being called a pirate, and there's a price on her head!
