Who is Rachel?

Rachel lost her job because of her drinking, but she still rides the train to London each day so her flatmate won't know. Her ex-husband Tom lives on the same street she passes, with his new wife Anna and their baby. Rachel watches another couple a few doors down, whom she calls Jess and Jason. One day she sees Jess kissing another man in the garden.

What happens to Megan?

The woman is Megan Hipwell, and the next day she is reported missing. Rachel was in that street the night Megan vanished, drunk, and woke with a head wound and no memory. She tells the police and Megan's husband Scott about the man she saw, Megan's therapist Kamal. The police see her as an unreliable drunk. Megan's body is later found; she was pregnant, and the baby was not Scott's.

Who killed Megan?

Rachel's memories slowly return, and she realizes that much of what Tom told her about her drunken behavior was false. That night she saw Tom with Megan. Tom was Megan's lover and the father of her baby. When Megan told him she would keep it, he killed her. Anna, finding a secret phone, reaches the same conclusion.

Rachel goes to warn Anna, and Tom confronts them both. When he attacks Rachel, she stabs him in the neck with a corkscrew, and Anna pushes it deeper to make sure. The two women tell the police the same story, and it is judged self-defense. Rachel moves away, stops drinking and begins to rebuild her life.
