After almost an entire lifetime spent in religious instruction, Gabriel returns to his small Irish town as the new preacher. But the town is full of drinking and gambling, and Gabriel's younger brother Jim and sister-in-law Caroline are no exceptions. Soon Gabriel learns that Caroline does not attend church, runs the local pub across from the church on the Sabbath, and refuses to have her child baptised. Jim, the flat-broke black sheep of the family, quickly becomes caught between his brother's beliefs and his wife's strong-mindedness. As a messenger of God, Gabriel believes he must save the townspeople, especially his brother, his sister-in-law, and the couple's unborn child. The battle for their souls brings about some surprising revelations on all sides.
