When the windshield of his commercial airplane shatters at 30,000 feet in the air, a pilot and his flight crew work to ensure the safety of the passengers and land the plane.

Directed by Andrew Lau, the film is based on a real-life incident in May 2018, when the cockpit windshield of a Sichuan Airlines flight shattered while the plane was flying 30,000 feet above the Tibetan Plateau. The co-pilot was sucked halfway out of the cockpit and passengers started losing consciousness due to low pressure.
