Using his knowledge as a scientist to develop a formula able to predict those offenders most likely to strike again, he sets out to protect future victims the law is powerless to defend. FBI agent Steve Patterson investigates crimes against those who have paid their dues for past mistakes. Recognizing a disturbing pattern of untimely deaths in recently released felons, he sets out to discover who's behind it. What he doesn't expect is to find another chance at love with the sister of the man he is chasing.
