"MAYDAY, MAYDAY, MAYDAY!" The Campground Kids get their feet wet on this oceanic adventure as they explore Acadia National Park. After their whale-watching expedition on the Unsinkable II, the family picks up Noah, Ethan's smug cousin, as they head to Duck Harbor Campground. The next day, the group returns from an early morning hike to find the campground completely deserted! Noah uses his trusty amateur radio to signal for help only to find that a hurricane is bearing down on their location.
