Jessica, the owner of Strings and Notes, a music store, and a musician (cellist) in her own right who only plays for her own pleasure, loves everything about Christmas. Seeing them in her favorite coffee shop, she sends special Christmas cards to the five most important people in her life. Those cards and the included messages from Jessica affect the recipients profoundly. The first goes to her best friend and business partner, Mimi, who, along with her husband John, have decided to face the lies that have crept into their marriage. The second goes to her younger brother Carter, a private in the military, he who is currently posted overseas and thus is away for Christmas for the first time. He has to decide whether or not to take a chance to express his romantic feelings for a fellow private, Angie, in light of the fact of he always sticking his foot in his mouth whenever he's around her, and they only possibly being together for a couple more weeks before they are off to wherever their next respective postings. The third goes to her and Carter's Aunt Lila, who raised them like her own after their own parents died when they were children. Lila's receipt of the card coincides with her noticing a handsome man walking his dog through the neighborhood - who she ends up learning are Tom and Blitzen respectively - a connection to both she feels even in not knowing their story. The fourth goes to Jax, someone she personally does not know, he a pop musician formerly in a successful boy band, their most famous song being "Luv U on Xmas" which has special meaning for her. Jax long ago walked away from the band for what ended up being a failed solo career. Especially now at Christmas, Jax has to decide to parlay whatever gain he can get off that one hit which he has come to hate, or be true to his heart both professionally and personally. And the fifth was going to go to her most recent boyfriend of three months, Wes, an optician, that is until he unceremoniously broke up with her. Instead, the fifth goes to Mrs. Miller, who was her first cello teacher and who inspired her to become a cellist. Instead of getting to Mrs. Miller directly, the card ends up in the hands of Luke, Mrs. Miller's adopted son, a photographer by profession who reluctantly works weddings more often than not to pay the bills, and who, during the season, volunteers as a Santa mostly at St. Mary's group home where he was once a resident himself. Like Jessica, Luke has been unlucky in love. While Luke just has not found the right person, he being able to tell within the first five minutes of a first date if there is even a chance, Jessica has had relationships much like the one with Wes, where she plays them out for as long as they last before each boyfriend comes to the realization that they are strictly going through the motions, most at around the three month mark. As Jessica and Luke begin to fall for each other, they may not face a happy ending together stemming from misconceptions of the other.
