Reverend Samuel (Preach) Preston is a full-time Christian evangelist traveling the country preaching the gospel of Jesus Christ. But Preach is on a mission - a mission to re-create the martyrdom of the original apostles of Jesus Christ. To his family he is father and grandfather. To the Christian world, he is a dedicated man of God. But to FBI agents Duncan Morris, Lynn Keller, and George Benjamin, he is a serial killer they must stop before he can kill again.
