Dateline NBC, or simply Dateline, is a weekly American television newsmagazine series. It was previously the network's flagship newsmagazine, but now focuses mainly on true crime stories with only occasional editions that focus on other topics.

For more than 25 years, Dateline has brought viewers investigations into some of biggest mysteries in America. This entry in the franchise takes a second look at some of the most mysterious cases of recent history. It explores the stories through firsthand accounts told by people who are close to the crime, including investigators who dedicated their time to the cases and family members who are still trying to confront the tragedies that befell their loved ones.

During a year-long investigation led by Adnan's new lawyer Erica J. Suter and Baltimore State's Attorney Marilyn Mosby, new revelations expose flaws in the original prosecution. As other potential suspects, suppressed witness testimony, and untested crime scene DNA come to light, a legal and political tug of war ensues, thrusting Adnan into chaotic uncertainty.
