After Jack and Lucy rescue a woman from freezing cold in the middle of Scottish mountains, they come to realize that the woman is not who she says she is and that she has not the best intentions.

Jack and Lucy set off for Christmas holidays, united in a family house located in the Scottish mountains. Instead of happiness and celebration they are greeted with an almost dead woman, Margaret, found in the freezing cold outside not too far away from the house. While the two wonder what in heaven's name is going on and who she is, there is a hellish plot brewing, a plot that could claim a life.—Samuel Miller
