In May 2018, 94-year-old Mary Gregory died in a house fire. Investigators ruled it a tragic accident, likely caused by a dropped cigarette. But they were wrong. This gripping true crime documentary uncovers the chilling story of how a harmless game of "Truth or Dare" exposed a murderer. A year after the fire, Mary’s step-grandson, Tiernan Darnton, made a shocking confession to his friends during a party. He revealed his "darkest secret"—that he had disabled the smoke alarms, blocked the exits, and started the blaze himself. From the initial accident ruling to the reopened investigation, follow the detectives as they piece together the digital evidence, the "kill list" found on his phone, and the game that finally brought a suspect to justice.
