Emergency Declaration 4K 2021 KOREAN

A passenger flight leaves Incheon for Honolulu. While a Seoul policeman follows his professional intuition to investigate the identity of an unknown person who posted a video on the Internet threatening to carry out a terrorist attack on an airplane, a criminal infiltrates the plane and sprays an unknown substance on board. Passengers and staff begin to show signs of infection with an unknown disease, it becomes clear that the ship has been subjected to a bioterrorist attack. The operational staff tries to get the plane to land, but it turns out to be not so easy.
