Humanity is nearly extinct. A perpetual and deadly Rain falls on the Earth. Men known as Junkers plunder goods and artifacts from the ruins of civilization. One such Junker sneaks alone into the most dangerous of all ruins -- a 'Sarcophagus City'. In the center of this dead city, he discovers a pre-War planetarium.

During a normal day at an underwater amusement park, an accident happens, placing half of the facility underwater. The path to the surface and the communication lines are cut off and 7 people are trapped. Many questions arise as to the legitimacy of the accident and whether or not those trapped there were brought there for a purpose.
