Ben Stein plays interviewer and narrator as he investigates what he calls a purge of scientists who question Darwinian evolution. He sits down with researchers like Richard Sternberg, who says he lost his position at the Smithsonian after publishing a paper favorable to intelligent design, and astronomer Guillermo Gonzalez, denied tenure at Iowa State amid the same controversy. Stein also interviews prominent evolutionary biologists, including Richard Dawkins and PZ Myers, pressing them on the theory's limits and on how dissenters are treated within universities and journals. The film walks the Berlin Wall as a visual metaphor for intellectual barriers, and travels to Auschwitz to argue that Darwinian thinking fed into Nazi ideology, a sequence that drew sharp criticism from scientists and historians alike. Structured as advocacy journalism rather than neutral inquiry, it builds its case entirely around the claim that academia enforces orthodoxy through firings, denied grants, and blacklisting. Whatever side of the debate a viewer lands on, the interviews and the specific careers it documents are the film's real substance.
