The series follows Las Vegas criminalists working for the Las Vegas Police Department as they use physical evidence to solve grisly murders in this unusually graphic drama, which has inspired a host of other cop-show "procedurals". The series mixes deduction, gritty subject matter and character-driven drama. The network later added spin-offs CSI: Miami and CSI: NY, which have both been cancelled after ten and nine seasons respectively.
Light Yagami is a 17-year-old ace student who is bored of school, life and the state of the world. One day, on his way home after school he fiends a black notebook with "Death Note" written on it. The first few sentences of the book state that everyone whose name is written into it is going to die through the power of a Shinigami. At first he discards it as a joke but later he realizes that it is the tool with which he can change the world to a place without crime or criminals. However, after the first criminals die, the authorities are forced to do something and send the legendary detective L to track down Light.
