Trailer for A24’s New Action Thriller 《Onslaught》

When genetically engineered super soldiers escape in the desert, an Army sniper fights to protect her young daughter. Adam Wingard directs the A24 action thriller starring Adria Arjona.

The story begins when a genetically engineered super-soldier unit deserts in the desert. A24’s synopsis presents a former Army sniper—not an ex-soldier—facing this threat to protect her young daughter. The setup brings the runaway troops and one family’s defensive struggle into direct conflict.

The protagonist is played by Adria Arjona. The official cast also includes Dan Stevens, Eric Wareheim, Reginald VelJohnson, Michael Biehn, Alex Pereira, Drew Starkey, and Rebecca Hall. Centered on the isolated desert setting and confrontations between armed figures, the trailer quickly presents the situation in which the protagonist must flee and defend herself with her daughter.

The film was directed by Adam Wingard of 《The Guest》 and 《Godzilla x Kong: The New Empire》. In production notes released by A24, Wingard explained that he made the film to return to his cinematic identity and said it was shot in New Mexico. He mentioned a scene in which the super-soldiers attack a trailer park, hinting that the threat extends to desert residential areas.

A24 released 《Onslaught》 in theaters on September 4, 2026. The official trailer introduces Wingard’s direction and the principal cast, and gives the same release date.
