Medical student Amy Brenner is spending the night on a locked psychiatric ward. Amy has been dreading her evening working on Ward D, the hospital's inpatient mental health unit. There are very specific reasons why she never wanted to do this required overnight rotation. Reasons nobody can ever find out. And as the hours tick by, Amy grows increasingly convinced something terrible is happening within these tightly secured walls.

Beautiful, charming, down-to-earth, and looking for a room to rent. She's exactly what Blake's looking for. Or is she? Danger lives right at home, and by the time Blake realizes it, it'll be far too late. The trap is already set.
