Brilliant but bored high school student Light Yagami suddenly finds himself holding the power of life and death in his hands—the power of the Death Note. He decides to rid the world of evil—by killing off criminals one by one. When the murders start to pile up, genius detective L is on the case, and an epic battle of wits unfolds.

L insists on setting up bugs and cameras in the homes of Chief Yagami and Deputy Director Kitamura—whom Raye Penber was tracking. But Light is a step ahead as usual—he knows he’s being watched.

After fifty days of confinement the killings continue, and Misa and Light are released. But L has devised a plan to ensure no more murders occur, and has Light's father, Soichiro, take the two for a ride that may be their last.

L, Light and Misa watch from the investigation team building and wonder who he is talking to. L wonders if Higuchi is talking to a shinigami. Rem convinces Higuchi to go to the station, but she has her own selfish motives for doing so.
