Natalie returns from a month-long business trip to find a stranger breastfeeding newborn twins on her couch—wearing the irreplaceable sapphire necklace her dead grandmother left her. Her CEO husband Ryan claims it's all a misunderstanding, but the woman, Claire, says they've been together for nearly two years and he gave her the necklace as an anniversary gift. As Natalie demands answers, she discovers their joint account is nearly empty, drained by over a million dollars in transfers she never authorized. But the financial betrayal is just the beginning: Ryan's phone reveals a meticulously planned double life, complete with a divorce attorney meeting scheduled for tomorrow morning. Now Natalie must untangle a web of lies that reaches far deeper than one affair—because everyone she trusted may have been working against her all along.
