On December 26, 1996, John and Patsy Ramsey wake up the morning after a loving family Christmas to discover their youngest child, six-year-old JonBenét, is missing, a chilling ransom note left downstairs. Later that day, John Ramsey discovers his daughter's body in the basement, revealing the shocking truth that JonBenét had not been kidnapped, but was instead sexually assaulted and brutally murdered in their own home. The Boulder, Colorado police, who had little practical experience in homicide investigations, quickly cast suspicion on JonBenét's family as the most likely suspects, fanning the flames of media scrutiny and largely one-sided reporting, turning the case into a national obsession. Twenty-eight years later, that obsession — and finger-pointing — hasn't gone away, and the murder of JonBenét Ramsey remains unsolved. From Academy Award nominated director Joe Berlinger, this three-part docuseries investigates the mishandling of the case by law enforcement and the media, ultimately revealing the relatively simple steps that can be taken to finally solve perhaps the most infamous cold case of all time. But will Colorado authorities finally take the necessary steps to bring the vicious killer of JonBenét Ramsey to justice and allow the family to finally have peace of mind?

As the murder of 6-year-old JonBenét grips the nation, a bungled crime scene and relentless media scrutiny of her parents stall the hunt for her killer.

Conflicting theories set the Boulder police at odds with the city's prosecutor. A legendary detective steps in and uncovers clues that shift the case.

After the grand jury decides on the Ramseys' case, suspicion falls on a pageant photographer. Years later, an email thread triggers a shocking arrest.
