You thought they were just staying for the weekend. They looked harmless enough - with only two suitcases and a cat in a wicker box. But soon things turn very, very dark. It happens slowly, yet so extraordinarily quickly. Now you and your sister must find a way to survive....

Rachel catches the same commuter train every morning. She knows it will wait at the same signal each time, overlooking a row of back gardens. She's even started to feel like she knows the people who live in one of the houses. Jess and Jason, she calls them. Their life - as she sees it - is perfect. If only Rachel could be that happy. And then she sees something shocking. It's only a minute until the train moves on, but it's enough. Now everything's changed.
