Cherringham is hit be a blizzard and Jack's sports car isn't really made for that much snow. When a ghostly figure steps out in front of his car, he ends up spinning around then in a ditch. Unhurt, he looks around to find the person he saw in the road but has no luck. Jack let the police know so they'll be on the lookout and heads home, after checking to make sure Sarah and her kids are okay. The next day, Jack walks to Sarah's and after some fun in the now, they head over to the pub and discover an old man in pjs and a dressing gown who was found by the pub owner in the snow the night before. Jack think this must have been the man he'd seen on the road and he and Sarah volunteer to drive the man back to the care home he'd "escaped" from.
Getting to the care home, they discover that the power is out and there are only 3 carers there to take care of too many older people, many with some form of dementia. Furthermore, they discover that one man is still missing. Jack fixes the emergency generator while Sarah helps take care of the old people and they wonder what's going on with the care home so decide to investigate. After they get things back on track, they head back to town and end up stopping near where Jack saw the old man the night before. As they work their way into the forest, Sarah discovers the poor frozen body of the missing man. They have a lot of questions: how did two men escape the home to begin with? Why is the home so understaffed? Who is in charge of the home? And why is one nurse terrified while another carer is openly hostile to the residents? Jack and Sarah put their heads together and work to solve the case.
