The documentary weaves together two strands: an examination of the problem posed by creationists who earn science education degrees only to advocate anti-scientific beliefs in the classroom; and a visually stunning raft trip down the Grand Canyon, led by Dr. Eugenie Scott, that debunks creationist explanations for its formation. These two strands expose the fallacies in the "debate," manufactured by anti-science forces, that creationism is a valid scientific alternative to evolution.
