It's a holiday season the Duncans won't soon forget! The adventure begins when the Duncans, who are en route to Palm Springs to celebrate the holidays with Amy's parents, are separated after Teddy (Bridgit Mendler) makes a snap decision to give up her seat on the flight for a free ticket. Unwilling to stand by and let her daughter travel alone, Amy (Leigh-Allyn Baker) also disembarks the plane only to discover the next flight to Palm Springs departs after Christmas. Meanwhile, the rest of the family arrive in Palm Springs, but things aren't any easier as Bob (Eric Allan Kramer) tries to care for Charlie (Mia Talerico) under the watchful eye of Amy's mom Petunia (Debra Monk); PJ (Jason Dolley) learns the pros and cons of his grandparents' pool and Gabe (Bradley Steven Perry) quickly realizes the downfalls of teaching grandpa Hank (Michael Kagan) how to play his video game.
