WATCH: Kate Mara Stars In New Trailer for Sci-Fi Thriller 'Morgan'

Kate Mara ("House of Cards," "Fantastic Four,") stars in the newest trailer for "Morgan," a sci-fi horror film that centers on a dangerous woman who may or may not be human.

"Morgan" stars Mara as a corporate troubleshooter who is sent to a remote, top-secret location, to investigate a terrifying accident. While there, Mara learns the event was triggered by a seemingly innocent "human" woman named Morgan, a mystery of both 'infinite promise and incalculable danger.'

Mara is joined by Toby Jones ("Captain America: The First Avenger,") Boyd Holbrook ("Wolverine 3,") Michelle Yeoh ("Crouching Tiger Hidden Dragon,") Jennifer Jason Leigh ("Hateful Eight,") and Paul Giamatti ("The Amazing Spider-Man 2.") Mystery woman Morgan is played by Anya Taylor-Joy, who made her horror debut in the cult-hit film "The VVitch."

"Morgan" is directed by Luke Scott -- son of prolific director and producer Ridley Scott -- and opens in theaters September 2.
