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 hand 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 twenty-three 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.
