On the morning of December 26, 1996, a frantic mother named Patsy Ramsey calls 911 to report that her daughter is missing and a ransom note was left on their back staircase demanding $118,000. As authorities investigate the disappearance, however, it quickly becomes apparent that not everything is what seems.

Or were parents John and Patsy hiding something? Maybe even a dark secret about their 9-year-old son, Burke? Let's find out.
