An ex-commando for the Israeli Defense Force is reunited with his estranged Christian father when they are recruited to participate in a time-travel experiment. A think-tank of the brightest physicists on the planet, working in secret for decades at the Technion-Israel Institute of Technology, has created a device that can manipulate the space/time continuum. Unable to verify a successful foray into the past, the physicists enlist the aid of the father, an eminent archelogy professor, and his adventurer son, to substantiate the placement of a subject into the deep past, from where he can never return. To mitigate theoretical time paradox interference the First Century is chosen as the temporal destination, and the father and son devise an ingenious way to communicate through the intervening millennia. As the father prepares his son for the journey, the two grow closer, and in a final act of love the son promises his father he will look for evidence of Jesus if the experiment is a success and he is placed in ancient Israel. The son departs, and the father spends a lifetime searching the Hebrew tombs of Israel for a message he never finds until he is forced into retirement because of what the Chancellor of Tel Aviv University considers to be increasingly eccentric behavior.
