Two old college pals, Asai and Jiyong, make their annual pilgrimage up a mountain in the middle of winter in honor of their friend Sayuri who disappeared there 16 years earlier. However, Jiyong seriously injures his leg in the middle of a violent blizzard. Overcome by cold and pain, he asks Asai to let him die here and save his own life. First, though, he confesses to a horrible secret that has been eating away at him. He was the one who killed Sayuri that fateful day, out of jealousy. The problem, if there is one, is that Asai finds a cabin nearby that they hadn’t seen because of the blinding storm. Once inside, the murderer’s confession takes on a whole new dimension, and let’s just say that the elephant in the room is more of a mammoth. To say that it’s going to be a long night would be an understatement.
