When a family finds a child in their yard buried in snow and suffering from frostbite, they try to warm him up to save his life. The child eventually awakes and tells them that his family is in danger, and so two men and a boy venture out to save their neighbors, if they can make it through the deep snow without freezing.

Some time in the near future, people begin mysteriously disappearing near a dangerously polluted river in Detroit. As these instances continue to occur, a local middle-aged woman begins to question whether the water itself may be to blame.
