Alexis Roberts is asleep when someone breaks into her home and attempts to assault her. Though she manages to escape serious harm, the invasion leaves her scared and shaken. The police investigate but Alexis has few details to share—she’s hard of hearing and couldn’t find her cochlear implant in the darkness. Was her attacker a stranger or someone she knows? Flashback to a year earlier when Alexis meets the man of her dreams. Attentive, charming, and fluent in American Sign Language, Marcus is unlike any man she’s ever known. Believing he is Mr. Right, Alexis agrees to marry him, but soon Marcus grows distant and no longer resembles the man who swept her off her feet. Then she makes a horrifying discovery—his first wife is missing and suspected dead. Now, in this gigantic house in an isolated neighborhood with no family or friends nearby, a terrified Alexis waits for the intruder to return.
