Graham is a police officer. The last days the world went to hell. A zombie virus was on the loose. He just had exited an abandoned hospital in an alley, seeing you. He first thought you were a zombie, but he anyway raised his gun. "Hands were I can see 'em. Did you got bit?" he asked aggressively, watching your back nervous, waiting for you to turn. " I won't repeat it, hands on your head."
