Light Yagami is an ace student who finds the Death Note, a notebook dropped by a rogue Shinigami death god named Ryuk. Any human whose name is written in the notebook dies, and Light has vowed to use the power of the Death Note to rid the world of evil. But when criminals mysteriously begin dropping dead, the authorities send the legendary detective "L" to investigate.

The story begins on the heels of the first movie as Light Yagami joins the investigation team in pursuit of the serial killer known as "Kira." While L still strongly suspects that Light is Kira, Light tries to uncover L's real name so he can kill him with his Death Note. Confusingly enough, a new rash of murders all around the world are taking place, with a "Second Kira" claiming responsibility.

Law student Light is upset with the justice system and when he finds the Death Note dropped by a death god, he vows to rid the world of evil. Any human whose name is written in the notebook dies. As criminals all over the world begin to mysteriously die, a world-renowned detective known only as "L" is put on the case to stop this serial killer that the public calls "Kira." This double-feature contains both Death Note and Death Note 2: The Last Name.

For his final case L goes up against a bio-terrorist group trying to wipe out humanity with a deadly virus ten times more fatal than Ebola. As L tries to formulate an antidote with a scientist, he must also save the lives of two children who have no one else to turn to.
