On an ordinary day in an ordinary high school in the United States, John (John Robinson), who failed to play truant from class, returned to campus under the pressure of his father; Elias (Elias McConnell), who liked photography, came to the school darkroom to develop photos after taking pictures of some people and landscapes inside and outside the campus; Jordan, who had a new girlfriend, was being talked about by girls who had had a relationship with him; Michelle, who was snubbed and depressed, came to the school library to help with the work. Outside the campus walls, Eric (Eric Deulen) and Alex (Alex Frost), who are often bullied, are taking a nap at home. They are so obsessed with Nazi images and violent games that they have ordered guns on the Internet. After the nap, the two men made a simple plan, dressed in US field uniform and holding submachine guns, walked into the campus and began to kill on a large scale.
