In a split second, Morgan's life changes for ever. A stranger hands her a baby, then jumps in front of a train.
Morgan has never seen the woman before and she can't understand what would cause a person to give away her child and take her own life.
When the police question Morgan, she discovers none of the witnesses can corroborate her version of events. And when they learn Morgan longs for a baby of her own, she becomes a suspect.
To prove her innocence, Morgan frantically tries to retrace the last days of the woman's life. She begins to understand that Nicole Markham believed she and her baby were in danger. Now Morgan might be in danger, too.
Was Nicole a new mother struggling with paranoia?
Or is something much darker going on?
