What secret does the Shroud of Turin contain to justify murder?

When scientists uncover a Vatican plot to discredit the Shroud of Turin, they risk their lives to find out why. Unbeknownst to all but a few people, the pope has authorized a dangerous experiment: clone Jesus. Not only are church authorities unprepared for what Jesus would say, they are less prepared for what Jesus would look like. Giving their secret project urgency is a similar experiment by a neo-Nazi cult with cloning ambitions of its own: splice the DNA of Jesus to that of Adolf Hitler.
