Three months after the zombie virus outbreak, the south has fallen completely, while the bitter cold of Northeast China has kept the zombie hordes at bay. Bi Yong, a bathhouse owner, and Gangzi, a bath attendant, are enjoying a peaceful life until a train brings zombies and shatters their calm. The two rescue Zhao Xue and form a team. Bi Yong uses the winter cold to make ice defenses against zombies and modifies docile zombies to assist with their operations. Gangzi handles close combat, while Zhao Xue carefully coordinates the team. They encounter various kinds of mutated zombies, and Zhao Xue's white-haired zombie mother dies protecting everyone. Their nemesis, Lü Cha, gathers a group to attack them, but the team joins forces to eliminate him. Meanwhile, a scientist working behind the scenes for Yuan Corporation continues releasing zombies for experiments. The team splits up and subdues the scientist, temporarily bringing the crisis under control. Everyone celebrates the New Year together at the bathhouse, just as a plane bearing Yuan Corporation's logo flies across the sky.
