A sobering look at the worldwide interest in eugenics in the early 20th century, director Peter Cohen's film uses archival film footage and long-unseen documents to track the evolution of the idea of using selective breeding to improve the human race. See how the controversial practice was used to justify sterilization laws in the U.S. and Sweden and research in the Soviet Union, and how it reached a chilling climax in the "racial hygiene"-obsessed regime of Hitler's Germany. 85 min. Soundtrack: English; photo gallery; trailers.
