Ace Pilot Ethan Cole had his license revoked after taking blame for an accident for his best friend Lucas Morgan, and was demoted to a janitor at the airline. Before a flight departs, he discovers a fatal wing crack defect, only to be dismissed and mocked by Captain Lucas Morgan and his girlfriend First Officer Grace Shaw. When a series of fatal crises hit the plane including loss of control in a thunderstorm zone, hydraulic system failure, fuel leakage and required water landing, the looked-down-upon janitor Ethan Cole steps up repeatedly, saving the day with his top professional skills. However, Lucas Morgan and Grace Shaw not only take credit for his work, but also create an artificial fault to frame Ethan Cole. Finally, with the intervention of the Civil Aviation Administration investigation team, irrefutable evidence including cockpit recordings, black box data and on-site footage is exposed one by one, and the truth comes to light.
