Jill Lassiter’s three-year-old daughter disappears from a playground only to return after 40 frantic minutes of searching, but the mother’s relief is short-lived --- there’s a tiny puncture mark on Sophia’s arm. When doctors can find no trace of drugs in Sophia’s system, Jill accepts she’ll never know what happened, but at least her child is safe. Except Sophia isn’t. Someone is watching the Lassiter home in an affluent Pennsylvania suburb, infiltrating the family’s personal and professional lives. As Jill faces every parent’s worst nightmare a second time, she must find out who has taken her daughter and why. Someone doesn’t just want Sophia for her own --- she’s out to destroy Jill’s entire family.
