When Maya receives a desperate 3 AM voicemail from her estranged twin sister begging for help, she drops everything and rushes to her aid—only to find the apartment empty and her sister vanished without a trace. The police dismiss her concerns, her sister's friends claim they haven't seen her in weeks, and the one person who promised to always have her back—her sister's charming fiancé—insists Maya is imagining things. But as Maya digs deeper, she uncovers secrets that make her question everything she thought she knew about her sister, their past, and the man she once trusted like family. Now someone is following her, her apartment has been broken into, and she's receiving threatening messages warning her to stop asking questions. Maya must find her sister before it's too late—but the closer she gets to the truth, the more she realizes the real danger might be coming from the last person she ever suspected.
