Both have had enough of their lives for a while and when Kaelynn's husband takes the kids to Florida for Christmas, they decide to switch places, as they often did when they were kids. Everything goes well at first, but Sophia gets a surprise when the kids' trip to Florida is canceled and they come home just as she's just met a handsome firefighter. In town, Kaelynn tries to manage Sophia's job, social life and strange roommate, with disastrous results.
