A carnival arrives in the city and, amid the hustle and bustle, Lisa meets a dog, Goldie, who leads her to a pirate ship owned by Captain Noah. Next thing she knows, she's heading out to sea.
Lisa wants to prove her worth aboard her new pirate ship home. Captain Noah knows how to sail the boat, Ava knows how to navigate, but what can Lisa do?
Noah loves the stories Lisa writes about their adventures except for one thing - they're not spooky enough. Or at least that was the case before an abandoned ghost ship drifts across paths with the gang.
The Captain is thrilled to have Lisa, Noah and Ava aboard his ship because now he finally has someone who can help him retrieve the sunken treasure chest hiding in the shipwreck below them. He even has an amazing submarine they can use.
