252: Signal of Life (2008)

At some point in the distant future, a massive, catastrophic earthquake strikes Tokyo, causing the temperature of the Pacific Ocean to rise meteorically and the largest typhoon in recorded Japanese history to sweep toward the city and inundate it with water. The Tokyo Fire Department and its team of crack rescuers swing into action, and shortly after they do, a distress call arises from an underground subway station - with repeated indications of the rescue code, 252 252, and the exclamation "We Have Survivors." It soon becomes apparent that the local rescue squad must attempt to save the survivors, doing so at the expense of their own lives and safety. Written by Nathan Southern
