A young TV news producer is raped and murdered in her apartment. Police identify two suspects, but both are cleared of any wrongdoing. The case stalls for more than a year, and then investigators turn to the Commonwealth of Virginia's DNA Databank which houses profiles of more than 8,000 convicted felons, and is the first of its kind in the nation. A comparison of the crime scene evidence with the Databank profiles results in Virginia's first cold hit in a homicide investigation, and reveals the identity of the killer.
