Marine Captain Jung-seok is driving his elder sister, her husband Chul-min and his nephew Dong-hwan to a ship that is meant to leave the Korean Peninsula, which is being swept by the zombie outbreak. On the way, he encounters a man and a woman with a young child who needs a hitch, but he ignores the family’s pleas and drives away.

Jung-seok then unwillingly decides to leave Dong-hwan and his mother behind and stops Chul-min, who returns after getting some supplies, from entering the cabin.:
