Dr. Regina Dickerson is a Catholic physician in San Diego who has discovered that there is a certain genetic marker that indicates the carrier is prone to psychotic violence. Working on blood
from prison inmates, her theory begins to prove itself time and again with violent offenders. As Dickerson’s work begins to show results and catches the attention of the media, people begin to
fear that witch hunts will result if forcible testing is carried out. Meanwhile, a race begins to find a cure. With science and religion at odds, Dickerson must find her own answers while
trying to escape those who want to put an end to her inflammatory research.
