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. In a cabin of the moving ship, an infected man turns into a zombie and infects numerous people, including Dong-hwan. 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. Four years later in Hong Kong, a guilt-ridden Jung-seok, with Chul-min and two other Koreans, are briefed by the Hongkongers of an operation that requires the four to return to the quarantined peninsula and retrieve an abandoned food truck which contains bags of cash, totaling US$20 million. The four arrive the following night and after some searching, they find the truck. The four escape the area unharmed with the truck, as zombies begin chasing them.
