Plot Progression

1. A Kidnapping Without Return — A child is kidnapped, and the kidnapper directs the family and police through telephone calls. The suitcase is dropped from a bridge, but the child does not return and the ransom disappears.
2. The Unreported Call — The 64 case continues to burden the local police. A mishandled second telephone call was concealed, and the failure to trace it threatens to expose the cover-up.
3. A Department Under Pressure — Mikami confronts a plan to put the local Criminal Investigation Department under headquarters control. He argues that removing its local chief would weaken the department and the wider local force.
4. The Press Confrontation — The police's initial withholding of information about a fatal accident angers reporters. Disclosure brings accusations of corruption, and Mikami's defense does not produce reconciliation.
