It's the start of Winter break in 1992, and four students from the local Christian school have signed up for a two day trip into the winter wilderness. Watched over by the trusted chaperone, the students are content to split their time between exploring the forest and snuggling up inside the cabin until it’s time to go home for Christmas.

However, strange things always linger and creep through the forest, and it’s not long before the chaperone instructs the students to stay inside for the foreseeable future. As the hours turn to days and food and water begins to dwindle, strange shadows stalk the outside, the chaparone seems to act stranger with each passing day, and the students begin to wonder if the big picture is even darker than what they could have ever imagined.
