When the mutilated body of a young woman is discovered in the Santa
Monica Mountains, LAPD Detective Jessica Allen knows this isn't the
work of a first-time killer. She's seen this MO before - two and a
half years ago on the other side of the country. Allen begins to
dig deeper and soon uncovers a terrifying truth. A sadistic serial
killer has been operating undetected for the past decade, preying
on lone female drivers who have broken down. The press dub the
killer 'the Samaritan', but with no leads and a killer who leaves
no traces, the police investigation quickly grinds to a halt.
That's when Carter Blake shows up to volunteer his services. He's a
skilled manhunter with an uncanny ability to predict the
Samaritan's next moves. At first, Allen and her colleagues are
suspicious. After all, their new ally shares some uncomfortable
similarities to the man they're tracking. But as the Samaritan
takes his slaughter to the next level, Blake is forced to reveal
that the similarities between the two men are closer than even
Allen suspects. With time running out and an opponent who knows all
of his tricks, Blake must find a way to stop the Samaritan . . .
even if it means bringing his own past crashing down on top of him.
