In the United States, there is a group of superheroes with supernatural powers called "Watchmen". The first generation of Watchmen helped the U.S. government win World War II, and the second generation of Watchmen helped the U.S. government win the Vietnam War. They are the guardians in people's minds during the war. But after the arrival of the peaceful age, they made people fearful, and people regarded them as trash, and the watchmen retired one after another. However, on this day, the watchman codenamed "Laughing Craftsman" was assassinated at home, and "Rorschach", who was also the watchman, decided to find out the truth. Rorschach is jealous of evil, he believes that everything is black and white, and there is no middle ground in his concept. As the investigation deepened, he found out that someone wanted to destroy the watchman organization, and he hoped that the watchman code-named "Dr. Manhattan" could help him. Doctor Manhattan is the only god in Watchmen with super powers, almost omnipotent. But he was disturbed and couldn't use his super powers, so he couldn't help. Soon the Soviet Union was about to move, and they were preparing to launch a nuclear war against the United States. At this time, Rorschach found out that the one who assassinated the watchman turned out to be one of them, the watchman code-named "Pharaoh". It turns out that all of this was manipulated by Pharaoh, who created the god-like Doctor Manhattan, and let the world see the doctor's ability to destroy the world. His purpose is to make those who want to start war afraid and dare not act rashly . Rorschach was devastated when he understood the truth. His world was either black or white, and he couldn't accept it. However, he also felt that the pharaoh's idea seemed to be correct. Perhaps this was the law of the world's existence
