Det. Walter Edmond responds to a homicide in Central City, where a young woman named Cayla Kelley has sustained multiple gunshot wounds and is found dead in the street. At the crime scene, a couple who claims to know the decedent approach NOPD. Det. Edmond quickly senses something is amiss and detains the couple.

Edmond collects surveillance footage that places Simmons at the crime scene with Cayla and issues an arrest warrant. A few days later, a ballistics match shows that the murder weapon that killed Cayla, killed another innocent victim named Eddie Matthews. This piece of evidence breathes new life into Det. Jameson Diesburg's investigation, who once feared the case would go cold. The detectives are shocked to learn Earl Simmons allegedly killed two people within four hours and team up to get Simmons off the street.
