Three-year-old Sophia Lassiter disappears at the playground only to return after 40 frantic minutes--but her mother Jill's relief is short lived. Jill is convinced the tiny dots on her daughter's arm are puncture marks. When doctors find no trace of drugs in her system, Jill accepts she won't ever know what happened during her daughter's absence and is simply grateful to have her home safely. Except Sophia isn't safe. Three months later, she disappears again. 2016.
