Though Sophia enjoys her life in Santa Monica, she longs for a holiday she doesn't have to work through. Her plans to go to Cancun for the holidays are dashed when her boss demands she work on a new project. Her twin sister Kaelynn is struggling too this Christmas, as it's the first since she and her husband separated and he is taking the kids to visit his parents in Florida. Desperate for any distraction she can get, Kaelynn offers to take on Sophia's workload so Sophia can get some much needed rest and relaxation at Kaelynn's home in Ohio. It isn't the first time they've switched places after all! Everything starts off well until Kaelynn's husband's Florida plans are ruined and he returns with their kids. Now Sophia has to try to convince Kaelynn's husband and children that she is Kaelynn, while her sister desperately tries to get back to Ohio in time to celebrate Christmas with her family.
