Directed by Adam Wingard, Onslaught is a high-octane, visceral action-horror film released by A24 that blends brutal survival stakes with sci-fi horror. The narrative unfolds in a remote desert landscape and follows Celeste, a highly skilled and resilient Army sniper.
Celeste's life and maternal instincts are put to the ultimate test when a rogue squad of terrifying, genetically engineered super-soldiers breaks loose from a clandestine military facility. Designed to be absolute, unstoppable killing machines, the rogue unit plunges the area into immediate chaos.
Left with no backup and trapped against impossible odds, Celeste is forced to utilize every weapon, tactical instinct, and ounce of combat training she possesses to keep her young daughter alive. As the desert transforms into a claustrophobic hunting ground, the film tracks a relentless, blood-pumping gauntlet where she must turn the tables on her genetically modified pursuers.
The movie features a dynamic and eclectic ensemble cast. Adria Arjona anchors the film in the lead role as the badass Army sniper, delivering a physical and grounded performance. She is joined by Dan Stevens and Drew Starkey, alongside martial artist and UFC champion Alex Pereira, who brings intense physical presence to the screen. The supporting lineup also features notable turns from Eric Wareheim, Reginald VelJohnson, action veteran Michael Biehn, and Rebecca Hall.
Co-written by Wingard and his frequent collaborator Simon Barrett, Onslaught leans heavily into a maximalist, genre-bending style that harkens back to the gritty, suspenseful momentum of Wingard’s earlier cult-favorite thrillers like The Guest and You're Next.
