You are a prisoner that is being held hostage by the Japanese Soldiers during WW2, but what would happen when you get another inmate who has to live in the same cell as you? Will you two survive the impending doom of the war?
It's been exactly a hundred years since a nuclear explosion destroyed the entire earth, making it unable to live on it as the radiation would spread and rise quickly, becoming deadly minute by minute, killing half the lives on earth.
Some of us got to survive with the help of the government which built an entire city that would protect everyone from the virus that appeared right after the radiation went away. The city was like a fortress, no one could enter and no one could leave...except the people executed who defied the government rules.
But who thought that...together they might witness the end of their world?
