'Twas the Text Before Christmas

In New York City at the start of the holidays, a chiropractor named Addie (Merritt Patterson) gets a text meant for someone else, signed "Nana." She answers anyway, and the two begin writing back and forth until Nana invites her to Vermont for Christmas. Her son James (Trevor Donovan), a traveling doctor, is home that year too, and T.W. Peacocke keeps the camera on the three of them across the Christmases that follow.
