In 1517, Martin Luther nails his ninety-five theses demanding reform of the Catholic Church to the door of Wittenburg Cathedral, setting off a period of upheaval, war, civil war and violence we now know as the Reformation.

In this age devastated by wars of religion, a young theology student adopts the cause of the heretics and the disinherited. Across the chessboard of Europe, from the German plains to the flourishing Dutch cities and down to Venice, the gateway to the East, our hero, a 'Survivor', a radical Protestant Anabaptist who goes under many names, and his enemy, a loyal papal spy and heretic hunter known mysteriously as "Q" play a game in which no moves are forbidden and the true size of the stakes remain hidden until the end. What begins as a personal struggle to reveal each other's identity becomes a mission that can only end in death.
