The emergency message about the coming attack of aliens is repeated on the broadcast. A sandstorm soon invades the space as the foreshadow of the arrival of aliens. It drives the people into a shelter. Instead of being frightened, the people enjoy the moment, wearing VR goggles and fall into the virtual world. However, one person accidentally discovers a “system vulnerability” on the CCTV monitor. She leaves the shelter. The world has become a ruins. She sees a strange bright light from the windows and moves towards it in the heavy smog… Do the alien attackers really exist?
