"Professor Batchelor Calwood leaves his university campus, torn by the riots of Vietnam protesters, to search for an ancient library buried near a monastery at Gaza in Israel. Unknown to him, an assistant has concealed in their luggage a new and deadly device that will allow terrorists to highjack and destroy airplanes. As the Professors archeological discoveries about the origins of Christianity begin to cause alarm in the Vatican, his accidental involvement with terrorists puts his own life at risk on the eve of the six day war between Israel and her neighbors."
