Here’s an official description:
This spin-off follows a new original storyline and introduces the unwritten chapter of DEATH NOTE and reveals how the legendary detective “L” (Kenichi Matsuyama) spends the final 23 days of his life.
The story begins as L takes on the “Kira” case, in which countless criminals are dying under mysterious circumstances. L successfully solves the case and stops Kira, but only after sacrificing his life, leaving himself with only 23 days left to live. For his final case L faces down a bio-terrorist group trying to wipe out humanity with a deadly virus ten times more potent than Ebola.

DEATH NOTE: L, change the WorLd features what happened before and after the two earlier DEATH NOTE events and shows DEATH NOTE fans the more human side of L that could not be seen previously.
If you live in San Francisco, the new Viz Cinema is having a special showing on August 25. Tickets are $25, but include a copy of the DVD and a poster. That’s a pretty good deal, and a neat way to commemorate the release.
