Onslaught (2026) guide: plot, cast led by Adria Arjona and Dan Stevens, Philippine release date, R-16 rating and where to watch Adam Wingard's action horror.

Onslaught plot: what the story is about

Out in a stretch of empty desert, a military experiment goes badly wrong. A unit of super soldiers, genetically engineered to be faster, stronger and far more ruthless than any ordinary fighter, slips out of control. With no chain of command left to rein them in, they turn their training on anyone in their path.

Caught in the middle is a U.S. Army sniper who is also a mother. Her priority is simple: keep her young daughter alive. Outgunned and outmatched on paper, she has to use every skill she has against enemies built specifically to win this kind of fight. The premise also points toward a government conspiracy behind the program, which raises the stakes beyond a straightforward fight for survival.

The film is a tight 92 minutes. It blends a military action thriller with a survival slasher. The violence is described as brutal and merciless, and the threat is relentless. Its tagline sums up the tone: “They unleashed their deadliest weapon on us.”
