When an early storm brings not just snow but a mysterious stranger to their doorstep, the Harts quickly realize this winter is unlike any they've faced before. Strange tracks appear around their home, and a shadowy figure lurks at the edge of their property, watching them with an unsettling, unblinking gaze. Seeking answers, Sable and Reed consult the village elder, Marcella, who reveals that they are dealing with a spirit of winter—a creature as old as the land itself, drawn to the cold and the darkness. With Marcella's guidance, they place protective charms around their farmhouse and keep their fire burning, hoping to ward off the spirit's sinister presence. However, as the winter deepens, the spirit grows bolder, testing their resolve and their bond. As they face each new trial together, Sable and Reed's love and determination are pushed to the limit, and they come to realize that surviving this winter will require more than just warmth and shelter—it will demand every ounce of courage they possess.
