Karl Glogauer is a disaffected modern professional casting about for meaning in a series of half-hearted relationships, a dead-end job, and a personal struggle. His questions of faith surrounding his father's run-of-the-mill Christianity and his mother's suppressed Judaism lead him to a bizarre obsession with the idea of the messiah. After the collapse of his latest affair and his introduction to a reclusive physics professor, Karl is given the opportunity to confront his obsession and take a journey that no man has taken before, and from which he knows he cannot return.

Upon arriving in Palestine, A.D. 29, Glogauer finds that Jesus Christ is not the man that history and faith would like to believe, but that there is an opportunity for someone to change the course of history by making the ultimate sacrifice.
