Rachel catches the same soulless commuter train each morning. Every day the train passes the scene of her old life, a life now occupied by another woman. She knows the train will stop and wait at the same signal each time, overlooking the row of back gardens in her old street, and she’s even started to feel like she knows the people who live in one of the neighbouring 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. When she discovers that the woman she calls Jess has disappeared, Rachel becomes a part of the lives she’s only watched from afar. As she involves herself in the investigation, she starts to uncover a web of tangled secrets that neither she nor anyone else was prepared for. Are the police correct in their suspicions – might she be a murderer?

Based on the worldwide smash novel and Dreamworks film.
