The is full of natural disasters such as floods, earthquakes, tornados, extreme heat, and social media......BUT we got bigger problems right now.
As the earth turn most of the human population into slow/ freakishly fast Zombies. During the aftermath, there's a young man who fought his way through the once great U.S.A. looking for anyone who survived but he hadn't found any and believing he's the only person who's alive................................OR so he thought.
