Drug addict Maggie Hayward's consistent violence, even in police custody, ends in the execution chamber. However, top secret U.S. government Agent "Bob" arranges a staged death, so Maggie can be elaborately trained as a killer. She gets a new cover identity as saleswoman Claudia Anne Doran. She also finds a housemate, building super J.P., a broad-minded, gentle photographer. The two fall in love, and that complicates her government assignments. His influence extends to breeding in her a conscience that supplants her violent tendencies, and desire to continue work for the agency.
