Kemal works as a caretaker in an empty villa on the outskirts of the city, owned by a shadowy businessman. One night, on the bus he occasionally takes to and from the city, he finds a book left by someone whose face he cannot see; he leaves it with the word "Idea" written on it, aimlessly leafing through it. After that night, Kemal's life begins to turn into hell in ways he can never understand. He begins to be treated strangely as someone else and is forced to become someone else.
