The Girl on the Train

Rachel Watson, a recovering alcoholic, faces the monotony of her life by commuting daily into New York City. Her days are marked by reflections on her past and the collapse of her marriage, creating a sense of isolation and despair.

During her train rides, Rachel becomes obsessed with observing her ex-husband Tom, his new wife Anna, and their neighbors Megan and Scott. This obsession grows as she seeks to distract herself from her own troubled reality.

Rachel's struggles with depression, stemming from infertility, led her to develop an alcohol addiction that influenced her relationships and career. Her drinking often resulted in embarrassing and harmful actions, particularly towards Tom and Anna.

At a barbecue organized by Tom's boss, Rachel's alcohol-fueled behavior leads to severe embarrassment, ultimately causing Tom to lose his job. This incident highlights the destructive impact of her addiction on her former life.

Rachel witnesses Megan kissing a stranger and, driven by jealousy and rage, confronts her. However, the confrontation ends in a blackout for Rachel, leading to unexpected consequences.

After the confrontation with Megan, Rachel wakes up in her own bed, covered in blood with no memory of how it happened. This alarming event coincides with Megan being reported missing, raising suspicions about Rachel's involvement.

Detective Riley questions Rachel regarding her whereabouts during Megan's disappearance, considering her presence at the scene suspicious. Rachel, desperate to provide answers, falsely claims to be Megan's friend during her interactions.

Amidst the investigation, Rachel discovers a picture of Dr. Kamal Abdic, Megan's psychiatrist, who she suspects was involved with Megan. This revelation shifts suspicion away from others as deeper emotional issues surface.

In a meeting with Dr. Abdic, Rachel hears about Megan's traumatic past involving the loss of her baby. This revelation sheds light on Megan's struggles, adding emotional depth to the investigation and implying the influence of past traumas.

As the investigation heats up, Megan's body is ultimately discovered, confirming she had been pregnant at the time of her death. This unsettling news creates a wave of tension, leaving everyone to confront the possible paternity of the child.

Scott confronts Rachel, angered by her deception and involvement in the case. The tension escalates to a boiling point, as secrets unravel and accusations fly, putting Rachel in a precarious position.

Sober and determined, Rachel warns Anna about Tom's potential danger. Their interactions lead to a pivotal confrontational dynamic that tests their resolve and solidarity.

In a climactic scene, Tom attempts to exert control over Rachel, leading to a fierce struggle. Rachel retaliates with a corkscrew, and with Anna's help, they manage to overpower Tom, resulting in his death.

Following the death of Tom, Rachel and Anna provide their accounts to Detective Riley, claiming self-defense. Rachel visits Megan's grave, reflecting on their complicated lives before deciding to embrace a new beginning.

In a symbolic gesture of change, Rachel chooses to sit on a different side of the train during her commute. This decision signifies her commitment to moving forward and seeking a healthier, brighter future.
