Young widow Joanna Watson is struggling to make a new home for her five-year-old son, Samuel, in the little mountain town of Settler's Fort. When she returns home from work to find Samuel and the woman watching him missing, with no lawman in town, she enlists a man she prays has enough experience in this rugged country to help.

Isaac Bowen wants nothing more than a quiet, invisible life in these mountains, far away from the bad decisions of his past. But he has a strong suspicion of who's behind the kidnapping, and if he's right, he knows all too well the evil they're chasing.

As they press on against the elements, Joanna fights to hold on to hope, while Isaac knows a reckoning is coming. They find encouragement in the tentative trust that grows between them, but whether it can withstand the danger and coming confrontation is far from certain in this wild, unpredictable land.
