The lights have gone off, planes are falling out of the sky, winter is coming and their teenage daughter has disappeared. Follow the Morrisson family as they struggle to cope in their new post-apocalyptic world. Soon, the Canadian wilderness disappears under a blanket of snow. With people dying around them from starvation or cold, they work together with their neighbours to survive. Stan and his wife find new strength and along with the local police force strive to offer encouragement to the town.

As they try to stay alive, they know that their child is out there somewhere. When winter is over, they set out to find out if she is dead or alive.
