Eli Roth’s latest horror film The Green Inferno is due out in the U.S. on September 25. Sky Ferreira makes her film debut as the lead character’s best friend. In a new short clip from the movie, Ferreira’s character Kaycee can be seen giving her best friend Justine a somewhat uncomfortable send0ff.

The clip is seemingly normal, too normal, until the last few seconds where things take a very abrupt and unexpected turn. There’s no doubt that Eli Roth’s new film will feature a lot of suspenseful twists that will grab the audience’s attention—this clip makes that pretty clear—but it will be interesting to see how Sky Ferreira does in her first film.

Watch the short clip above.
