The story tells about a flight that took off from Brussels. At this time, the sudden change in solar activity killed all the creatures that were exposed to the sun. Therefore, the plane that was lucky enough to escape the disaster tried to fly westward to hide in the darkness. The flight included rich people, poor people, young people, old people, civilians, soldiers, etc. They had only one goal: to survive this solar catastrophe... The problem is that some people would do anything to achieve this.
