Three years after losing his family in a Christmas Eve accident, grieving Paul Wanlass hasn't just given up on Christmas, he's given up on life. He can't imagine anything to keep him here, not his work as a computer repairman, not the residents in his Salt Lake City neighborhood, and certainly not the idea of connecting with someone new. When a stranger knocks on his door, claiming to be picking up a laptop, Paul allows him in but discovers the man has a very different mission in mind. The mysterious stranger's name is Gabriel, and when Paul finds himself opening up to his visitor, Gabriel tells him, 'I wouldn't, if I were you. It's not what you think.' He then departs without another word. Paul brushes the experience aside as some trick of the imagination-- until he crosses paths with a young widow and her bullied son, who've also received a visit from Gabriel. Before he knows it, these two fill his life with chaos, commotion, and excitement he hasn't felt in years. The three of them are convinced Gabriel brought them together for a reason-- but why? And who, or what, really is this Christmas stranger?
