A desert facility built to create the perfect soldier ends up producing a threat no one on base can contain, and one mother has to stop it before it reaches her daughter.
What is Onslaught about?
Onslaught opens with a breach: a squad of genetically engineered super soldiers gets loose in an isolated desert compound, and whatever chain of command was supposed to handle that scenario has already failed. Adria Arjona plays an Army sniper whose priorities narrow instantly to one thing — her young daughter is somewhere in the blast radius of what's coming. Dan Stevens and Drew Starkey round out a cast caught between military protocol and pure survival instinct, while Michael Biehn brings the weight of a veteran actor to a story about soldiers who were never meant to be fully human in the first place. Director Adam Wingard, known for staging action with a clear sense of geography and escalating stakes, treats the compound itself as a trap: corridors, checkpoints, and open desert all become obstacles between a mother and the one thing she's willing to burn the base down to protect. The engineered soldiers aren't framed as a faceless horde so much as a design flaw turned lethal, which keeps the tension personal even as the scale of the threat grows.
About the cast
Adria Arjona leads as the sniper-mother at the story's center, with Dan Stevens, Drew Starkey, and Reginald VelJohnson filling out the base personnel and Michael Biehn adding a veteran presence to the ensemble.
Context & significance
Made in the United States and directed by Adam Wingard, Onslaught sits squarely in the military-thriller action space, built around a single, high-stakes premise rather than a sprawling mythology. The genetically engineered soldier angle gives the action a sci-fi edge without pulling focus from the central rescue.
