The married couple, Adam and Amelia, both of them in their 40s, are considering separating, but Amelia’s therapist suggests a weekend getaway. Adam reluctantly agrees to go with her on a weekend getaway during a snowstorm to stay in a converted chapel, a place for which Amelia has won a free stay. The place is almost deserted, weird things start happening, and they don’t know who arranged for their free stay and sent the invitation in the first place.
