A fresh start. A safe neighbourhood. Or is it? You've moved back to your hometown, into a luxury gated community that's designed to keep intruders out. You think your family is safe, but you couldn't be more wrong. Your nine-year-old son says there's a man living in the attic. You keep hearing noises up there when you're all alone, but when you check, the loft space is empty. And then your daughter shows you something on her phone - a video of a man walking around inside your house while no one is home - and you start to panic. Why would a stranger target you? Unless they're not a stranger at all.
