Hyun-soo's father is a lazy and passive older yellow-haired young man. He and his father are also his daughter's grandfathers, and they run a small grocery store by the Han River. Hyun-soo also has an archer's aunt and a handsome and impulsive uncle. In the disaster, dad watched his daughter Hyun-soo being taken away by the monster, and he was convinced that her daughter would be fine. So my family and I imagined how to find Hyun-soo. However, the family was controlled by the government health department, claiming that they were afraid of the virus. In order to avoid virus infection, Hyun-soo's father was quarantined. One night, my father overheard my daughter calling for help. It turned out that Hyun-soo was trapped in a very inconspicuous place under the bridge, holding the mobile phone left by the deceased around him and calling his father for help.
Dad expressed his wish to save his daughter to the police, but he was laughed at and rejected, and called him a mental derangement. In desperation, in order to rescue her daughter as soon as possible, the family fled the hospital in a thrilling chase. To this end, they found an underground intermediary, got a disinfection car, a bridge engineering drawing, a rifle and bullets, dressed up and went straight to the bridge. To this end, they spent all their savings. In order to save Hyun-soo, Grandpa died heroically in the fight with the monster. Later plots were written in accordance with the law of beginning, inheritance, turning and integration. The family experienced various difficulties and unexpected dangers through various methods, and finally killed the monster. Unfortunately, Hyun-soo's life was not saved, but the little boy who suffered with her survived.
