A Christmas to Remember (2016) on Netflix

Plot summary

Jennifer Wade hosts a New York lifestyle show called Home Style and has just taped a Christmas special, although she no longer keeps the holiday herself. Her friend and producer, Paula, offers her a chalet near Aspen, and Jennifer sets out alone; her boyfriend, the sportscaster Brad, stays behind in the city. In a snowstorm near North Creek, Colorado, her car leaves the road. She comes to with a head wound, a mild concussion and no memory of who she is, and no identification with her. John Blake, the town veterinarian, a widower of three years and father to Jamie, Kyle and Daisy, finds her on the highway and brings her home. Nobody in town recognizes her, and the family calls her Maggie.
