A Christmas light shines bright in the midst of the darkest winter.

With Christmas only a few weeks away, Sam and Jessica Morgan look forward to celebrating the joyous day together. But when they’re awakened by the smoke alarm in the midst of one quiet night, they barely make it outside before their beloved house is engulfed in flames. Meanwhile, single mom Julie Newton and her seven-year-old daughter appear on Jack Sawyer’s doorstep, thanks to bad weather, a broken-down car, and a dead cell phone battery. And though Jack, still mourning the loss of his wife, feels none of the holiday spirit, he can’t turn them away. As Sam and Jessica become perpetual guests in others’ homes, trying to piece their future back together, and Jack finds his frozen heart melting day by day, it soon becomes clearer than ever that miracles can happen even in the humblest of settings.
