When 6-year-old Sam Kettering manages to escape after being kidnapped, FBI Agents Lacey Sherlock and Dillon Savich join forces with the boy’s father Miles—an ex FBI agent—to pursue his kidnapper, a creepy, charasmatic Southern evangelist.

As if the kidnapping case weren’t enough, Savich and Sherlock are at the same time desperate to find the cold-blooded killer of three high school math teachers in the Washington, D.C. area.
