Monster on the Han River

Kang Dou (played by Song Kanghao) is an ordinary and somewhat confused middle-aged man. He lives with his family with his daughter Xuan Shu (played by Go Ah Sung), runs a small shop by the Han River, and leads a quiet and peaceful life. Kang Dou's father Hee Bong (played by Byun Hee Bong) is a kind old man, and his younger brother Nam Il (played by Park Hae Il) is the only college student in the family, but he is unemployed and has no job. He often complained and drank heavily, and was dissatisfied with reality. Younger sister Nam Joo (played by Bae Doo Na) is an archery athlete, but she often loses her weight at critical moments. One day, people gathered on the bank of the Han River and were surprised to find an unknown monster that they had never seen before climbing on the pier of the bridge. Suddenly the monster rushed to the shore and rushed into the crowd of onlookers. Kang Dou wanted to escape with his daughter immediately, but Xuan Shu was kidnapped by the monster. This ordinary family suffered an unprecedented blow, and the whole city felt like it was facing a formidable enemy. How should they face the monster?
