Documenting the series overview
The setting of the Walking Dead is after onset of the worldwide zombie apocalypse. The zombies, also known as "walkers" move across living human beings as well as other creatures with the purpose of eating them and they are attracted by noise like gunshots and various scents such as that of humans. Though earlier it seemed that only the humans scratched or bitten by walkers could turn into other walkers. However, it is revealed relatively earlier in the series that all of the living human beings carry that pathogen which is responsible for mutation. The mutation gets activated after death of the host of pathogen. The only way to kill a walker permanently is destroying its body or damaging its brain.
The series is centered on Rick Grimes, which is the deputy of sheriff and he wakes up from the coma. While he was in the coma, the world has been conquered and taken over by the walkers. Rick then becomes leader of the survivors group from Atlanta, Georgia as they try to protect and sustain themselves against attacks from walkers and other groups of survivors by any means necessary for staying alive.
