All That's Left follows two journalists and their friends in post-apocalyptic United States as they travel from the fallen east coast megalopolis Opportunity back to Los Angeles, crossing through a harsh wasteland overrun with zombies— only to find out that there is a lot more life left than what the protected cities want them to believe. On their journey they meet dozens of people living their lives as peaceful as possible away from military forces, corporations, and corrupt governments; and they learn that the same mutated ghouls that took down Opportunity are spreading rapidly through the country, destroying everything in their path.
Will this finally be the end of the world as we know it?
