Ango Ishikawa is a detective with smarts and a keen sense of
observation. He's in a great physical shape and also highly ambitious.
Ango also only focuses on his work and his personal life is pretty much
non-existent.
One day, a former police officer is killed by a gun
shot. Ango goes to the scene of the crime, but is shot in the head by
the killer who is lurking at the crime scene. Ango hovers between life
and death. At that time, he thinks to himself "where do people go after
they die?" and then "I don't want to die." A miracle then happens. Anglo
survives with the bullet still lodged in his head. He goes back to
work.
A new murder case takes place. When Ango goes to the crime
scene he notices a boy who looks like he is about to cry, but only Ango
is able to see the boy. The boy is the one who was killed. Since Ango
was shot, he can now see and talk with the dead.
