The Girl On The Train

Rachel (Emily Blunt) takes the train back and forth to Manhattan every day. Whenever she passes by her old house with her ex-husband (Justin Theroux) , she will be upset by the memories and the fact that he is in a happy family with his new wife (Rebecca Ferguson). One day, on her way into the city, Rachel witnesses something so shocking in Megan (Haley Bennett) and Scott (Luke Evans)'s backyard that it rocks her to the core.  Soon after, when Megan goes missing and is feared dead, Rachel tells the police what she believes she has seen.  But can Rachel trust what she thinks she witnessed, or is she entangled in the crime itself?
