Once, the Earth, the only planet that has been bustling, was a vast area which you couldn’t explore to the end. Now, humans are caged inside a circle because the Outside is peril to everyone. Do you remember the story of Noah’s ark? The abolishment and cleansing of evil? It has occurred again. This time it wasn’t a deluge. It was “the Mist.” Where did the Mist started no one knew. All that could be gathered was that it becomes bigger and bigger every day. It was just a mist. That was what everyone once thought. No one knew that if you stepped into the Mist, out can never be an option again. There were hundreds endeavors to figure it out, but none succeeded. A rope was tightly secured on a man's body. He stepped in. And, when the rope was pulled back, it was cut on where it was still visible. Years later, a miracle happened. The mist stopped growing, saving five small countries in the desert land. However the people were trapped, not in the limited circle, but in anxiety of the Mist growing again.
