Light Yagami finds the "Death Note," a notebook with the power to kill, and decides to create a Utopia by killing the world's criminals, and soon the world's greatest detective, "L," is hired to find the mysterious murderer. An all out battle between the two greatest minds on earth begins and the winner will control the world.
Two Japanese friends accidentally kill their boss and dump his remains in Black Fuji, a mountain/landfill hybrid. This leads to poor results when the chemicals of the landfill mix with the corpse (and many other corpses) to give rise to a zombie infestation in Tokyo.
