Spain 1468 - A land where Christians, Muslims and Jews have lived in tolerance for centuries. That time is ending. A young King and Queen proclaim themselves Catholic Monarchs and start an Inquisition. Jews who had converted to Christianity are accused of secretly sabotaging the Christian faith. They become the pawns in a game of chess with dire consequences. Thousands perish in a ritual called the act of faith. In Zaragossa, the inquisitor is assassinated - setting off a wave of reprisals. Mothers will die to protect their children - and the highest in the land will pay the ultimate price. It is the beginning of the Spanish empire and a long dark night that will last for centuries.
