Emily Blunt plays an FBI agent in the upcoming thriller Sicario, which is quite the departure from her most recent role in the dark musical Into the Woods. On Tuesday, Lionsgate released new photos from the film ahead of its debut at the Cannes Film Festival this month.

The story follows Kate (Blunt) as she joins an elite task force stationed on the border between the U.S. and Mexico. Kate and her team battle against the tense drug wars, and the journey leaves her questioning everything she believes in as her morals are pushed to their breaking point.

Blunt is joined in the cast by Benicio Del Toro, Josh Brolin, Victor Garber and Jon Bernthal. The film, directed by Denis Villeneuve and written by Taylor Sheridan, will debut in select theaters beginning on Sept. 18, followed by a wide release on Sept. 25.
