When 19-year-old Stacey Stites' body is found half-naked by the side of the road, her fiancé, police officer Jimmy Fennell, is cleared as a suspect. DNA is found to match Rodney Reed, a local man suspected in other sexual assault cases and he is sentenced to death. A decade after the crime, Stites' former fiancé is imprisoned for sexually assaulting a woman in his custody. When new forensic evidence casts doubt on the timeline of the crime, evidence shows Stites' death may have occurred while she was at home.
