`Cold Case Files', one of A&E Network's most popular and successful series of all time, chronicles the re-examination of long-unsolved crimes and the journeys of law enforcement personnel who reopened them. With the use of forensic advances and new evidence, police and detectives attempt to crack the cases and clarify unanswered questions. Each story is brought to life through cinematic dramatizations and first-person storytelling from the detectives and loved ones who lived through the harrowing experiences. Bill Kurtis narrates.
