Detective Sergeant Rebecca Frye is attempting to solve a series of sexual assaults and is constantly finding herself running into dead-ends at every turn.
Finally, she gets a break in the case, a witness, one person who may help 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. Amidst professional conflicts and a growing mutual attraction, the two women become reluctant allies in the battle to stop the perpetrator before he strikes again.
