It is the winter of 2011, half a year after the Great East Japan Earthquake. A magazine journalist named Ken and his friends (Fumio, Taku, and Sanpei) visit the evacuation area within a 20-km radius around the Fukushima Nuclear Power Plant to conduct research. As they are reporting, holding video cameras in one hand, they discover one old house in the forest. When they pass through the gate and prowl around the garden, Sanpei's foot gets caught in an animal trap. Then, one old person appears from somewhere.
