When television news reporter Hope Martin (Lynda Boyd) breaks a story about mercy killing, Detectives Leary and Shannon start digging around for more details, and Da Vinci calls a Coroner's Inquest to force Martin to reveal her source. The issue of euthanasia is divisive and as the investigation proceeds Da Vinci finds himself at odds with the police and his superiors about the reality and the ethics of what happened. His elderly father's recent debilitating stroke further complicates his response.

Danny Leary is back in town, but the reunion with his older brother Mick is far from idyllic. It looks like he is hooked on drugs and, unbeknownst to Mick, hanging around with two hoods that turn up dead.
