Rachel Watson, devastated by her recent divorce, spends her daily commute fantasizing about the seemingly perfect couple who live in a house that her train passes every day, until one morning she sees something shocking happen there and becomes entangled in the mystery that unfolds.
The only good thing about this movie is Emily Blunts performances. The rest of the movie is a badly conceived melodrama with a plot from a soap opera. It tries to be clever like Gone Girl, but most people have figured the twist out just based on the poor editing.
