I saw it and I thought it was very compelling. They named the Hitler double that was actually shot & killed in the Bunker and then burned, the body the Russians found. And they showed the route the top Nazi’s took out of Berlin through the sewers and eventually making it secretly to somewhere in the Med if I remember then on to a U-baot for the trip to Argentina. I think it certain if that is the true story, that those Nazi’s had to have the help of some state actors including the Vatican, and I think it stated or at least hinted that it was likely the Jesuits that set up and maintained the rat lines from Europe to South America for the escaping Nazi’s.
I don’t believe the story but it’s a classic fantasy that will never die.
