Voice (JP)

Hikari, a voice profiler, pins down the hostage-taker's identity using voice analysis, as Higuchi and his son Daiki come across a woman being attacked.

Higuchi discovers the car deserted by the white-faced man and his partner, Junna, the abductors of Daiki; Ishikawa, aided by Hikari's special skill, traces Junna.

A boy has been abducted, and Higuchi firmly believes that Tsukada is the perpetrator. Following the leads found at Tsukada's home, Higuchi ventures to an abandoned factory, all while the boy's safety is at risk.

Chisato, an ECU member, is kidnapped by her ex-boyfriend Maezono. Hikari suspects that Chisato is hiding out at Maezono's villa but Higuchi and Ishikawa find Maezono stabbed there.

Higuchi, abducted by the white-faced man, wakes in a dry well. He radios ECU for help, but interference stymies Hikari's team. Meanwhile, a voice from the speaker mounted in the well forces Higuchi to confess his past crime as a police officer.
