You meets Fatal Attraction in this up-all-night story of suspicion, obsession and motherhood.

One ordinary fall morning, Kelly Medina gets a call from her son's pediatrician to confirm her upcoming "well baby" appointment. It's a cruel mistake; her son left for college a year ago, and Kelly's never felt so alone. The receptionist apologizes: there's another mother in town named Kelly Medina, and she must have gotten their numbers switched.

For days, Kelly can't stop thinking about the woman who shares her name. Lives in her same town. Has a son she can still hold, and her whole life ahead of her. When Kelly just happens to bump into the single mother outside that pediatrician's office, it's simple curiosity getting the better of her. But that curiosity quickly turns to obsession, and when one Kelly disappears, well, the other one may know why.
