From Executive Producer Dick Wolf, this true crime investigative series follows veteran prosecutor Kelly Siegler, and her rotating team of seasoned detectives, as they travel to small towns across the country and help local law-enforcement agencies dig into unsolved homicide cases that have lingered for years without answers or justice for the victims due to lack of funding and proper forensic technology.
