EMERGENCY DECLARATION

‘Emergency Declaration’: If an aircraft faces a potential disaster, and normal flight can no longer be maintained, the pilot calls for an unconditional landing.

Veteran chief police detective In-ho (SONG Kang-ho) receives a tip about a man threatening a terrorist attack against a plane. While investigating, he discovers that the suspect has actually boarded flight no. KI501. Despite his phobia of flying, Jae-hyuk (LEE Byung-hun) decides to go to Hawaii for the sake for his daughter’s health. At the airport, he is distracted by a strange man who hangs around, speaking to them in a menacing way. Flight no. KI501 departs Incheon Airport for Hawaii, but soon afterwards a man dies for mysterious reasons. Fear and chaos spread quickly, not only inside the plane, but also on land. Hearing this news, Transport Minister Sook-hee (JEON Do-yeon) sets up a counterterrorism task force and calls an emergency meeting in order to find a way to land the airplane.
