Sky Prison is a plane specially designed by the United States to transport the most dangerous criminals in the United States. Cameron (Nicolas Cage) boarded this plane not because of his heinous crimes, but because he applied for a flight in order to give his daughter a gift on her birthday. He behaved well in prison, and the warden agreed to his request. However, there was a problem-a group of murderers were escorted on this plane. The detective was very careful about the dangers that might appear at any time, but what was hard to guard against was that during the flight, the gang of thugs still held all the police on the plane hostage, and Cameron was forced to help them complete the escape mission. The federal forces on the ground decided to shoot down the plane and catch all the madmen. How should Cameron, who was in danger, escape from this sky prison?
