While there, he meets a motley crew of colourful characters. One night, a neighbour unwittingly reminds him of his dark past and he finds himself withdrawing from society again. Meanwhile Kenji, a detective from Tokyo, arrives in Kyoto on a lead that a murder suspect is in the city and about to strike again. Their paths intersect, to devastating effect.
