An anthology film consist of 7 short stories directed by several different directors, which are based on 7 moments since the founding of People's Republic of China.
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, but the captain managed to land the plane safely.
