When Paul Blair's wife is killed by a young drunk driver, he decides to dedicate his life to keeping the youth of his church from bad influences. And if that means bringing down the wolves who tempt them, so be it. When Paul finds that one of his own "flock" has adopted and escalated his own murderous strategies, he joins forces with the boy in a bloody crusade of vengeance upon the unholy.
