To help sell the work they're doing in this documentary, they point out that geolocation work by the True the Vote people helped solve a murder. Only that story isn't true. They later acknowledged as much to NPR. That pretty much tells you everything you need to know about this film.
They also apparently poured through hundreds of hours of surveillance video for clips of alleged "mules" dropping off ballots at drop boxes, but never once do they show the same person at more than one box. Obviously, that would have been a slam dunk, but we're just supposed to take their word for it.
Basically, this is just another grift. D'Souza gets a little money, and True the Vote more donations for their "work." That Fox News, who has their own problems over bogus voter fraud claims, won't even promote this, should tell you enough.
