Dr. Robyn Sparks is a veterinarian with a dark secret: she moonlights as a self-appointed vigilante, who deals her own brand of justice to animal abusers by murdering them. If you do bad things to dogs, Robyn does bad things to you.
She Bites tells the story of a talented veterinarian who dispenses brutal judgment. Her work with sick and injured animals provides Robyn with a view of life's most tender moments as well as a view of man's most brutal behaviors.
Robyn's regular habit of sending bad people to the pet crematorium is interrupted when she meets Jack Williams, a damaged detective who is fighting his own demons. Their relationship is a roller coaster ride of tangled emotions and legal close calls.
Ultimately, Robyn has to make a choice: whether to continue down her destructive path and kill a twisted psychopath turned professional dog fight promoter, or to pursue a romance with a cop who believes morality is best served by the hand of the law.
