Universal Pictures has released a new trailer for "The Girl on the Train (2016)". It gives a glimpse into the life of Rachel Watson, portrayed by Emily Blunt. Her life becomes a mess after her recent divorce. She is involved in a mysterious case after her ex-husband's nanny goes missing.

The trailer opens with Rachel saying, "I used to watch this perfect couple. They were the embodiment of true love." When Megan Hipwell (Haley Bennett) goes missing, Rachel tries to help find her. Rachel says in voiceover, "I saw her from the train. She was with this man... just for a second."

When she tells her ex-husband Tom (Justin Theroux) that she tries to find his nanny, he doesn't think she is helping anybody. Rachel is then suspected for a murder as she seems to be confused about what happened the night Megan went missing.

Based on Paula Hawkins' best-selling novel of the same name, the film centers on a woman named Rachel who is devastated by her recent divorce. She spends her daily commute fantasizing about the seemingly perfect couple who lives in a house that her train passes every day, until she sees something shocking happen there one morning and becomes entangled in the mystery that unfolds.

The film also stars Luke Evans, Allison Janney and Rebecca Ferguson (II). "The Girl on the Train" hits U.S. theaters on October 7.
