The British inquest into the deaths of Princess Diana, Dodi Al-Fayed, and driver Henri Paul forms the spine of this Timeline documentary, which reconstructs the crash in the Pont de l'Alma tunnel and the years-long legal process that followed. Archival news footage, courtroom material, and interviews trace the questions the inquest was set up to settle: whether Diana and Dodi were engaged, whether she was pregnant, whether a white Fiat Uno seen in the tunnel that night was ever identified, and whether Henri Paul's role in the crash was what it appeared to be. The film lays out the forensic and eyewitness evidence presented to the jury, including blood-alcohol findings on Paul and the paparazzi pursuit that preceded the collision, and follows the conspiracy claims that the crash was orchestrated, weighing them against the inquest's eventual verdict of unlawful killing through the negligent driving of the following vehicles and Paul's car. It stays close to the official record rather than speculation, letting the inquest's own findings carry the narrative.
