When returning on an international flight, captain Shen Yanzhou encounters an extreme thunderstorm. The right engine catches fire, the cabin loses pressure, and three hundred and twenty-seven lives hang by a thread. Shen Yanzhou requests an emergency landing, but is told to land on a construction runway. Lu Wanlin—the ex-wife "abandoned" by him at their wedding five years ago—has blocked all runways and forces him to make a full-cabin broadcast admitting to infidelity and slapping himself. To save the entire aircraft, Shen Yanzhou defies orders and risks an emergency landing on the construction runway, successfully saving everyone, only to be falsely accused by Lu Wanlin as the person responsible for the accident.
