A team of civilian experts, including a criminologist, a psychotherapist, and a medical biophysicist, re-examine the 1982 cold case of Patricia Roach, a 26-year-old nurse found dead in her basement after a fire. The squad meticulously reconstructs the crime scene and analyzes forensic evidence, including the nature of the ligature used and the positioning of the body, to challenge the initial ruling of suicide. As they delve deeper into the circumstances surrounding her death, they uncover new leads and question the credibility of key figures, including her ex-husband and a doctor who worked with her, in a quest to finally bring justice to a case that time forgot.
