While investigating a terroristic threat that goes viral online, Korean authorities discover that a suspect has recently boarded an international flight bound for the United States. When a healthy passenger on the same flight suddenly dies a gruesome death of unknown cause, panic erupts both in-flight and on the ground. With steadily decreasing fuel and international refusals to offer aid, the captain and crew will be forced to take unprecedented emergency measures in an attempt to save the lives of their passengers.

After losing her laundry store to a fire incident, a single mom Duk-hee receives a call from a bank offering a generous upfront loan so she takes it right away. But soon after, she finds out that she has become a victim of a voice phishing scheme. Devastated, Duk-hee turns to the police for help, only to be more disappointed that there is no hope of retrieving her money. At the moment of despair, Jae-min, the phisher who tricked her, rings her phone once again to tip Duk-hee off about the criminal organization that locked him up and coerced him to make voice phishing calls from China. With that call, Duk-hee makes up her mind to investigate this case for herself and take a plane to China with her friends.
