A team of civilian experts, including a criminologist, a private investigator, and a medical biophysicist, re-examine the 1968 cold case of 19-year-old Lynda White. By applying modern forensic analysis and geographic profiling to the decades-old evidence, the team uncovers disturbing patterns that suggest White's murder was not an isolated incident but part of a series of crimes committed by a single, highly mobile serial killer. As they piece together the timeline and location of the crimes, the investigators work to bring closure to the victim's family and potentially identify a predator who may still be active.
