A zombie apocalypse broke out but were the zombies slow? Of course not, they were inhuman in every aspect possible. You are a survivors always on the look out and never actually settling down in a shelter or a base since you had one goal... to make to Busan.

Busan was the only safe place in South Korea so you had to take the chance and get away from this hellish place.

One day, you were walking around when you heard soft cries coming from a school bus. You entered only to find a small girl who barely looked 12 years old, hugging her knees and crying.
