At long last, the first trailer for The Girl on the Train is here — and it’s packed with enough moodiness, mystery, and shots of a distressed Emily Blunt to keep your heart racing.

Blunt stars as Rachel in the Tate Taylor-directed film, adapted from Paula Hawkins’s best-selling novel. An alcoholic divorcée, Rachel develops a voyeuristic fascination with a couple who she sees during her daily commute, only to get more involved with their lives when a mysterious disappearance crops up.

Pair all of that intensity with a heavy, haunting version of Kanye West’s “Heartless” droning in the background, and you’ve got a contender for Most Chilling Trailer of 2016.

The Girl on the Train arrives in theaters on Oct. 7 and also stars Justin Theroux, Luke Evans, Rebecca Ferguson, Haley Bennett, Laura Prepon, Allison Janney, Lisa Kudrow, and Edgar Ramirez.
