The Inheritance freighter is remodeled for comfort of its passengers and crew—including the kids and the monkey who were rescued from the Palmyra Island adventure. High tech surveillance is managed by tech guru—the hairy giant Wally, and the ship is secretly super armed by the Hearst Castle Security Team run by Brookstone, who becomes a welcome friend and ally.
Luke and his adventurous friends battle surfing gangs on the beach. They have to deal with drug smugglers threatening to take over the California marina town where old friends live in their boats, and where the father of The Inheritance's Captain Jay is a dealer in antiquities.
Twin sisters, Amber and Crystal, bring romance to Luke and Theo, much to the guys’ protestations.
They will run into more troubles once they set off on the high seas for Peru in Part 2 to rescue the medical clinic from earthquake and hurricane damage. But there is plenty to do and lots happening before that!
