Story

The story begins when a mysterious virus outbreak spreads across a major city. Scientists and authorities struggle to understand the infection as more people become victims. The situation quickly turns into a disaster, forcing officials to isolate affected areas to prevent further contamination.

Among those trapped inside the infected zone is Professor Kwon Se-jeong, a researcher who becomes one of the few people searching for answers. She discovers that the outbreak is connected to a dangerous experiment that created a new type of infected threat.

As chaos spreads, a small group of survivors searches for a way out. They must move through abandoned locations while avoiding infected creatures that become more aggressive with time. Every decision becomes a matter of life and death.

The survivors soon realize that escaping the infected area will not be easy. Limited resources, growing fear, and disagreements between the group create additional challenges. Some people want to save others, while some only care about their own survival.

During their journey, they uncover hidden information about the virus. The truth forces them to question whether the outbreak was a natural accident or something created intentionally. These discoveries change their understanding of the danger they are facing.

The infected creatures become the biggest threat. Unlike traditional zombies, they show unpredictable behavior and increasing strength. This makes every encounter more dangerous and forces the survivors to adapt quickly.

The movie balances large-scale action scenes with emotional moments. Characters must decide how far they are willing to go to survive and whether saving humanity is worth risking their own lives.
