Forensic expert Maggie Gardiner continues her uneasy partnership with vigilante homicide detective Jack Renner to investigate the murder of a newspaper copy editor.

A copy editor at the Cleveland Herald is found hanging above the grinding wheels of the newspaper assembly line. Forensic investigator Maggie Gardiner has her suspicions about this apparent suicide, and when the evidence suggests murder, Maggie has no choice but to place her trust in the one person she doesn't trust at all. Jack Renner is a vigilante with his own code of honor. In the past, Jack has used his skills and connections as a homicide detective to take the law into his own hands, all in the name of justice. When more newspaper employees are slain, Jack may be the only person who can help Maggie unmask the killer-- even if Jack is still checking names off his own private murder list.
