Brit, a 28-year-old single mom near Columbus, is drowning in newborn sleep deprivation and freelance deadlines when strange things begin: warm bottles she didn’t make, toys moved, a baby monitor humming with a man’s voice. One night she hears laughter from her son Owen’s room and finds the crib empty—only a neatly folded onesie remains. On the floor lies a silver cufflink engraved “M.K.” She calls her ex-husband, Mason, who coolly admits he’s been entering her home at night and soon returns with Owen like nothing’s wrong.

Shaken, Brit changes the locks, installs cameras, and files for an emergency restraining order. In the attic she discovers a hidden box of baby items—some personalized for Owen—and a notebook in Mason’s handwriting documenting her sleep patterns and entries like, “Soon she won’t even notice when he’s gone for good.” Police review her footage and a neighbor’s doorbell video showing Mason climbing through a window, and arrest him for stalking and break-ins.

A search of Mason’s apartment reveals a fully furnished nursery stocked to match Owen’s needs—and, above the crib, a photo of Brit sleeping. Detectives conclude he was preparing to take Owen permanently. With the cufflink, notebook, and videos, the case against Mason solidifies as he faces multiple charges and likely jail time, while Brit pursues legal steps to cut ties.

Weeks later, Brit and Owen are safe but hyper-vigilant—locks replaced, cameras rolling, motion lights flaring at the slightest movement. She sleeps lightly, haunted by the image of herself above that crib and the question that won’t let go: if she hadn’t woken to that empty crib and found the cufflink, would she have ever seen her baby again?
