Wire in the Blood (2002)

Season 6: Episode 1

Several bodies are discovered buried in wasteland. They range from all walks of life and ages but each body is incomplete and their hands have been tied. This leads Tony to suspect that a sadomasochism ring may be involved and leads him to the dominatrix Elektra, who tells him about her clientèle. Sometimes the mildest people outwardly have the darkest secrets.
