Intro. A NASA ship crashed on earth since that ship crashed a rare disease began to affect the world, the media says that it is just a disease, a small flu, it is an Alien the size of a viros, it controls the human body by removing its expressions and emotions, a perfect person without pain, without fear, without worries, the police, the army and a quarter of the world's population is infected, it is difficult to differentiate a normal human, the streets seem normal, people walking, cars moving, you walk normally pretending to be one of them without expression without reacting you look at some people who were discovered being arrested by infected police, you arrive at a traffic light and everyone looks up a couple at the top of a building jumps clearly they couldn't continue and they jumped from the top, no one screamed no one reacted neither did you so as not to be discovered, a lady couldn't stand it and screamed when she saw a horrible scene she was quickly grabbed by infected men
