Fired for embracing creationism and rejecting Darwinian evolution, Australian professor, Dr. Noel Mason, feared his career was over. Unemployed, he wrote a book entitled "Scopes Revisited". It was a tremendous success and led to a summer visiting professorship at the University of Tennessee. While there, he participates in a televised debate with world-renowned evolutionist, Dr. T.M. Sheldon, and much to his surprise, won. Enraged over the humiliation of Dr. Sheldon, someone close to him sets out to terrorize the Masons.
