Qi lin zhi yi

the long version

A man is stabbed in the chest, then breathes his last on Nihonbashi Bridge. In trying to pin down the man's reason for dragging himself to that spot while so grievously injured, detective Kaga Kyouichirou finds out that he was on pilgrimage. His family has no idea as to the pilgrimage's purpose, but a word from the detective has caused a change in one man's heart...and a father makes a life-or-death decision.
