A detective has a tight deadline to crack a case that could claim the lives of millions in this crime drama, a spin-off from the Desu Notu (Death Note) franchise. L (Kenichi Matsuyama) is a cop with a serious sweet tooth and a fondness for gadgets who has been handed a very important assignment. A group of environmental radicals who want to decimate the Earth's population in the name of a greener world have gotten their hands on a potent man-made virus that could wipe out half the globe if it is released. It's L's job to track down the eco-terrorists and see that the virus is kept under wraps, but after signing his own name in the Death Book, he's given himself only 23 days to bring the radicals to justice. L: Change the World was the opening-night attraction at the 2008 Udine Far East Film Festival and was a major box-office success in Japan.
