Deputy District Attorney Paige Callen is being stalked, and the man stalking her is motivated, methodical, and relentless. The police aren't merely one step behind Paige's stalker; they're stumped. So Paige's father, retired Judge 'Iron Gene' Callen, instead hires retired San Francisco P.D. Inspector turned private investigator Bob Farrell, to the dismay of the local police. The cops know all-too-well Farrell's reputation as a reckless wild card. Judge Callen, however, knows Farrell as a man who never lets the rules get in the way of getting the job done.
