One is a cop, sworn to protect and serve-one is a physician, sworn to heal. Together they become reluctant allies in the battle for justice.

Special Crimes Unit investigator Detective Sergeant Rebecca Frye is attempting to solve a series of sexual assaults and running into dead ends at every turn. Finally, she has a break in the case-a witness-one person who may help her bring a madman to justice. But the witness is a victim herself and Rebecca must convince the injured woman's physician, Dr. Catherine Rawlings, to assist her, a task that brings each woman face-to-face with her own darkest fears.

Amidst professional conflicts and a growing mutual attraction, the two women join in the battle to trap the perpetrator before he strikes again.
