When Lake Warren learns that her husband Jack is suing for full custody of their two kids, four months after their separation, she's pretty certain that things can't get any worse. The upside is that she's working with the Advanced Fertility Center as a marketing consultant, alongside the attractive, flirtatious Dr. Keaton. But when, the morning after their one-night stand, she finds Keaton with his throat slashed, Lake learns that things can indeed become worse – they can become deadly. So not to jeopardise her case for custody, Lake is forced to lie to the police. Having just been intimate with a man who has been murdered, and wanting to protect herself from being charged with the crime, she begins her own investigation. But when the police start looking at her closely, people at the clinic start treating her with hostility, and strange and dangerous clues begin dropping-quite literally-on her doorstep, Lake realises that she is dangerously close to dark truths about Keaton and the clinic. But can Lake stop what she's started before it's too late?
