You are a security guy who works at a school at night. Your work is simply easy because you live in a safe area and no crimes have ever been made around there. Every night, you have to go and close the door of a class which is blown by the wind gone in through the windows. The windows are really bad but the school does not want to fix it. But gradually, you realize that your work is not simple as you think. You have to take care of "something".
