Onslaught character posters featuring Adria Arjona and Dan Stevens

Get ready for a bloody adventure, because A24 is gearing up to unleash a new action horror spectacle titled Onslaught, directed by the genre-savvy Adam Wingard.

The film promises a visceral experience, blending intense action, science fiction, and creature feature elements. It marks a return to the hard-edged, high-stakes genre filmmaking that established Wingard as a master of tension, drawing on influences from hits like You’re Next and The Guest.

The story centers on Celeste, a former Army sniper who has sought a quiet life raising her young daughter. This peace is violently shattered when a rogue squad of genetically engineered super-soldiers escapes from a secret military facility, unleashing chaos across the desert. Now, Celeste must harness her deadly skills to protect her family from the terrifying fallout.

The official synopsis perfectly captures the explosive premise: When a rogue squad of genetically engineered super soldiers break loose in the desert, a badass Army sniper must unleash hell to protect her young daughter.

The cast assembled for this mayhem is stacked with talent. Adria Arjona steps into the role of Celeste, grappling with unimaginable pressure as she confronts the threat. She is joined by Rebecca Hall as the enigmatic scientist Frau Kammler, and Dan Stevens as Dr. Kammler, who is deeply involved in the genetic super-soldier program.

The action is further amplified by an incredible ensemble. Alex Pereira brings his real-world fighting experience to the role of The Butcher, a figure of immense intimidation, while Michael Biehn plays Baylor, the leader of the elite mercenary team tasked with containing the crisis. The film also features Eric Wareheim as Kovacks and Reginald VelJohnson as Josiah, bringing the fractured community closer to the center of the conflict.

This isn’t just a story; it’s a collision of worlds. With Wingard returning to his roots in intense genre filmmaking, and co-financed by A24 and Onslaught will hit theaters on
