A sadistic serial killer has been operating undetected for a decade, preying on lone female drivers whose cars have broken down. The press dub the killer the ''Samaritan,'' but with no leads, the investigation grinds to a halt. That's when Carter Blake shows up to volunteer his services. Although Blake is skilled at hunting men, Allen and her colleagues are at first suspicious. But as the Samaritan takes his slaughter to the next level, Blake must find a way to stop him-- even if it means bringing his own past crashing down on top of him.
