Kate finds evidence suggesting her recently deceased husband David may have been a serial killer. While going through David's things to find documents for a work project, Kate discovers a locked box containing a young girl's photo, lock of hair, and list of names. Her internet search reveals one of the names was a suspected murder victim. Shocked, Kate calls her friend Jane for help, but Jane dismisses Kate's findings, not wanting to tarnish David's memory. Distraught, Kate burns the photo of the girl in her chimenea, crying as her husband's face appears in the flames.
