If her past catches up with her, it could be deadly. After a vicious attack, Brittany Mullins recovers but has no memory of who she is or what's happened to her. She has keys to a recently rented apartment, but the police are convinced the name on her driver's license is someone who doesn't exist. No family has come looking for her, and as Brittany prepares to leave the hospital, she's alone. Desperate to know who she really is, she turns to Jules and Becky, hoping the detectives can use DNA testing to confirm her identity. While they wait for her results, the best friends dig into the few clues they've uncovered about Brittany's life before the assault. They suspect she's in hiding-from someone or something dangerous. When a mysterious man stalks Brittany, Jules and Becky decide to protect their client until they determine how he fits into her past. As they work to unravel the man's agenda, Jules is convinced there's more at stake than they imagined, and the case becomes personal. Then, as friends and family gather for a wedding, Brittany goes missing. Becky panics, especially when she realizes Jules is nowhere to be found either.
