The 29-year-old working man has neither achieved fame nor fame. He accidentally turned into a mutant with a fish head and a human body because he rashly participated in a drug trial. He dreams of becoming a new social person who reports the truth and exposes injustice. He is assigned to investigate the authenticity of the fish man, which accidentally sets off a wave of social unrest that shocked the whole country. The unemployment rate of young people is rising year by year. They feel desperate about society but are powerless. The appearance of the fish man has become the spiritual sustenance of the new generation. However, under the manipulation of big companies and the media, the wind direction of public opinion has turned again... Director Quan Wuguang boldly dissects the ugly aspects of contemporary society, satirizes the media's deification and demonization, carefully explores the division and opposition of the people, and wraps the cruelty and cold-bloodedness of human nature with absurd fables. "The Elegy of the Fish Man" is like a magic mirror, reflecting the deformed society where chaos prevails today, and capturing the metamorphosis of capitalism with a fearless eye. Lee Kwang-soo, who became famous for the well-known Korean variety show "Running Man", plays the leading role for the first time and brilliantly interprets the confused generation facing difficulties.
