Based on a real event, an easy Korean domestic flight bound for Gimpo takes an ill-fated turn when one of the passengers, Yong-dae (Yeo Jin-goo), hijacks the plane with a bomb, demanding to change the flight’s path to North Korea, where his brother lives. With the captain (Sung Dong-il) losing his eyesight from the initial bomb blast, co-pilot Tae-in takes over the flight and fights to save the lives of the passengers, along with the flight attendant Ok-soon (Chae Soo-bin).
