A former colleague of Togusa's named Yamaguchi calls and asks him to look at some sensitive data related to the Laughing Man case. Before Yamaguchi can arrive with the material, however, the car he is driving swerves off of the road and explodes.

Aramaki allows Togusa to investigate Yamaguchi's death and Togusa is able to retrieve the information that his colleague wanted him to look at. The information could implicate high-ranking officials within Police HQ.
