The Ross kids leave their extravagant New York City penthouse and head off to Camp Kikiwaka. Together Emma, Ravi and Zuri must navigate the hijinks and curveballs thrown by the owner of the camp, Gladys, who with the help of her sneaky niece Hazel, is out to get them because of her decades-old rivalry with their mom.

Emma and Ravi resume their role as CIT’s bringing with them the experiences from their first summer at camp. Together with Zuri, her best friend and bunk-mate Tiffany, the cheerful head counselor Lou, the camp heartthrob Xander, and the hilariously imaginative Jorge, the campers embark on new and exciting adventures during their stay at Camp Kikiwaka. The friends welcome an unexpected camper with a dubious past named Griff, Xander gets to showcase his musical talents, familiar faces return for a visit and special friendships are formed and solidified, all the while overcoming unforeseen encounters that arise.

Returning to camp, the campers find some changes around them.

After purchasing Camp Kikiwaka—for one dollar—from the Ross siblings, the always cheerful Lou is adjusting to her new duties as camp director with her usual brand of over-the-top enthusiasm. She’s thrilled to be reunited with campers Destiny, Finn and Matteo, who have returned for another exciting summer full of fun and friendship. Lou also welcomes some new faces, including camp counselor Noah, an upbeat and enthusiastic actor from Hollywood; Ava, a tenacious counselor from the big city; and Gwen, an eccentric new camper who has spent her entire life living off the grid.

Back for another exciting summer at the sometimes struggling Camp Kikiwaka in rural Maine are the enthusiastic camp owner/director Lou, counselors Ava and Noah, and returning campers Destiny, Matteo and Finn, who are all ready to tackle new and hilarious adventures.

Lou, Parker, Destiny and Noah arrive at the soon-to-be Kikiwaka Ranch in Dusty Tush, Wyoming, where Lou must convince the surly owner, a.k.a. "The Marshal" to officially sell the property to her. In the meantime, counselors Noah and Destiny have their hands full with the newly arrived campers, including Bill, a no-nonsense descendant of famous cowboy Bill Pickett who prefers roping cattle to hanging out with friends; Winnie, a fearless girl who's earned the nickname "Wild Winnie" by breaking the rules and occasionally blowing things up; and Jake, a laid-back, easy-going boy who also happens to be a video-gaming fanatic.

The hijinks continue at Kikiwaka Ranch with Lou, her right-hand man Parker, plus counselors Destiny and Noah along for the ride. Cowboy Bill, daredevil Winnie and gamer Jake are also back for another summer full of excitement and new adventures.
