Ferocious Captain Firebeard and the crew of the Horrible Haddock rule the high seas. But the dastardly pirates meet their match when they kidnap a small, feisty girl called Molly as she sails to visit her granny. But Molly refuses to cower in fear.

She knows something the pirates don't - the real pirate to fear is none other than Molly's own mum, and she won't be pleased to find her daughter kidnapped!
