Carly Sagan, a female detective who grew up in a group foster home for abused children, keeps her past a deep secret from friends and co-workers. When a young woman is murdered and her body left on the grounds of the foster home, her investigation puts her on the trail of a serial killer whose victims have only one thing in common: they were all once residents of the foster home -- Safe Harbor. Carly knows her job and has been on a lot of cases, but this one is different-- because the closer she gets to finding the killer, the more difficult her own memories become.
