Landing in Alaska, the physician and Nyssa encounter a group of people in a most unusual house, cut off not only from the severe climate but by their person secrets and obsessions.

But when fatal creatures start roaming outside, and a terrifying finding is made inside the house, the physician realises that Brett has unleashed an unimaginably historic force.
