Princess Diana died because a drunk driver careened into a pillar -- so the official story goes, but a new show casts doubt on that ... and even raises the specter of foul play.

"Celebrity Crime Scene: Princess Diana" takes a hard look at the evidence and raises serious questions about driver Henri Paul's condition at the time of the crash. Fact is, Paul may not have been drunk at all.

Using state-of-the-art A.I. technology, the show recreates the crash from angles never before seen, and 2 mysterious cars -- one inside the tunnel and one outside -- raise questions about whether this was really an accident or something far more sinister.

Paul may have been forced into the tunnel and then greeted inside by a blinding light.

"Celebrity Crime Scene: Princess Diana" is now streaming on Hulu.
