Modern Europe.

Civilization collapsed due to an infectious disease of unknown origin, and about 12 years have passed.

Some of the infected continue to move after death and are called "zombies" by the people. However, they are no longer the true danger to humanity.

Following the collapse of civilization, many wild animals mutated. These beasts—massive, violent, and abnormally prolific—roam the land, threatening the lives of survivors.

Nations and major cities are lost, but humanity is not extinct.

People live in small settlements, farms, churches, abandoned factories, and old castles, surviving through agriculture and trade. Electricity and communication technology are still used sparingly in some areas, but medical supplies and daily necessities are chronically scarce.

In this world, zombies, mutated animals, resource shortages, and human conflict are everyday realities.

Living in this post-apocalyptic world are people who have chosen different paths.

Cole and Elliott, a raider team that survives by stealing supplies.

Nathan and Jamie, a guard team protecting a small village.

And Tae-jun, a hunter who continues his journey all alone.

The fates of these men, who once lived in the same village, are about to cross once again amidst the remnants of civilization.
