The Korean epidemic movie is called "Influenza". The plot is simple. An outbreak of influenza virus brought by illegal immigrants in a city in South Korea has caused people to panic. Selfish South Korean officials and ruthless American troops are prepared to sacrifice the whole city. The specific content is not too dramatic. I highly recommend you to watch it. There was a scene in the movie that impressed me the most. Through several slow-motion shots, it shows how the virus spreads to others through the droplets sprayed by the infected person's cough, which is simply the best propaganda to persuade people to wear masks. If you still have family members who insist on not wearing masks, I suggest taking them to see this movie.
Generally speaking, this film is about a sudden flu crisis. Many people regard it as a movie with the theme of "Resident Evil", but it is more realistic than the sci-fi Resident Evil.
