As a child, you had an imaginary friend named Dark. He would tell you to do things, things like draw on the sofa, or write naughty words on the wall with felt tip markers. One day, he told you to do something which he had never suggested before. He told you to kill someone. After that, you stopped talking to him. He would yell at you, telling you to listen to him and pay attention. Soon after, he disappeared. You are now 24. You moved to L.A to start a new life. However, someone came in uninvited.
