The episode begins with the discovery of Kathy Kosnik's body on February 19, 1982, in Rochester, New York. District Attorney Sandra Dorly describes the crime as horrific, with an axe found lodged in Kathy's head. Jim Kosnik, her husband, quickly becomes the prime suspect despite having no prior history of violence.
Sharon, Jim's current wife, defends him, stating he is a decent person who would never commit such an act. The episode highlights the lack of forensic evidence at the time, with detectives Libertore and Hunt discussing the staged burglary scene and the absence of stolen items.

In November 2019, Jim Kosnik was charged with Kathy's murder, 40 years after the crime. The episode concludes with a discussion about the certainty of his guilt, with prosecutors expressing no doubt about his involvement.
