South Korean director Lee Ok-seop's first feature film "A Catfish Saves the Earth" conquered the audience with its whimsical plot and won the Best Film at this year's Osaka Asian Film Festival. The film invited a catfish to act as a storyteller. The story originated from a "sex X-ray" that inexplicably leaked out of the hospital. The nurses were panicked and guessed who the protagonist of the mystery film was. At this time, the heroine's sixth sense erupted, and she actually suspected her loser boyfriend, triggering a series of out-of-control plots. In addition to satirizing the relationship between people in modern society, the film's shocking ending also opened the audience's mind.
