When Pennsylvania State Trooper Jim Duncan responds to a murder scene at a local mining company, the call hits close to home. The victim, Lonnie Butler, is a friend and neighbor who was just beginning to get back on his feet after a year of financial difficulties. Despite entertaining out-of-town family, Jim vows to stay involved in the case.

Meanwhile, Fayette County Assistant Public Defender Sally Castle faces an ethical dilemma. Her newest client, Ethan Haverton, may be deeply involved in Lonnie's homicide. Technically, Sally could break privilege, but she chooses not to, a decision that put her at odds with Jim.

As the investigation continues, the rift in Jim and Sally's friendship deepens. Can the battling couple patch the break and bring the killer to justice-or will their discord allow a friend's killer to go free?
