Frozen Memories.A hiker gets caught in a severe blizzard while climbing a mountain trail so he takes shelter in a shack only to realize he's not alone. A shivering old man is huddled in a corner of the shack. As the hiker rests, he recalls how his son Takeru had to go to the hospital, but made a promise to him to climb the mountain with him when he gets out. His wife, Shinobou, worries about waiting for them, but the hiker calms her down by telling her that this won't be the first time he's left her alone while he hikes. Suddenly, he hears a sound and he asks the old man what it was. The old man shushes him, telling him, "It's coming again..." He grabs the hiker by the shoulder and demands that no matter what happens, do not open the door until the blizzard passes. A while later, the hiker awakens to hear that the ringing has stopped. Suddenly, he hears Takeru outside the shack. The hiker is about to open the door when the old man stops him. The voice on the other side of the door asks if he's sad because Takeru died, leaving him and his wife sad and alone. The hiker tosses the old man aside, but the old man still begs him not to open the door. He's the last survivor of his hiking group. Whatever is on the other side of the door took all the others. The hiker finally remembers what happened to Takeru: he died from complications of the surgery. When the blizzard finally passes, the hiker calls his wife to tell her he's coming back. When he goes outside, all he can find is a pile of snow suspiciously shaped like a child...
