Set ten years after the events of previous films Death Note and Death Note 2: The Last Name. In 2016, society is afflicted with cyber-terrorism. The Death Note is a supernatural notebook that grants its user the power to kill simply by writing a person's name on its pages. Six different Death Notes fall to the human world, the maximum number of notes that can exist at once. In the midst of this, two new individuals inherit the DNA of Light Yagami and L and must play a deadly game of cat-and-mouse once again.
