Day of wrath (2006)

At the height of the Spanish Inquisition, high-ranking noblemen begin dropping like flies, with alarming frequency and unexplained violence. But can local 16th-century sheriff Ruy de Mendoza discern who's responsible when no one wants to cooperate? After all, before Mendoza can even identify the bodies, the crime scenes are mysteriously cleared - and the villagers pretend the murders never happened.
