At 3:14 a.m., lab tech Hannah tests her two-year-old son's blood and finds the impossible: he cannot be hers. Husband Grant calls her a cheater, but the DNA reveals the boy is his child with his mistress—while Hannah's real son lives in that woman's house, abused and unnamed. Following clues—a blood type, a dying voicemail, a car app, a bitten sippy cup, a red birthmark—she takes both sons back and makes every liar answer in court. This time, she is not asking for permission.
