Onslaught (2026)

In a remote facility in New Mexico, Nazi scientist Dr. Hans Kammler conducts research to develop a trio of super soldiers on behalf of the United States government. Three subjects, dubbed Crybaby, Cockroach, and the Butcher, were selected from US military personnel based on a demonstrated ability to survive and kill without mercy. Through surgical modification and psychological conditioning, they have been imbued with enhanced strength, endurance, durability, muscular control, night-vision, and a relentless drive to kill.

Government agent Baylor observes an exercise in which regular soldiers test the trio's abilities. All three seemingly die from cardiac arrest, but have in fact consciously lowered their heart rates to appear dead. When their supervisors unknowingly enter the arena, Hans, Baylor, and Baylor's men are all killed and the trio flee from the facility.

A former Army sniper named Celeste manages a nearby trailer park with her daughter Daisy. Celeste tells Daisy about a fellow soldier who challenged her to a fight. The soldier, who became the Butcher, chose Celeste because he believed she was an easy target. Celeste won by kicking him in the testicles.

The trio slaughters everyone in a truck stop and head to the trailer park in a stolen truck. A government operative named Cyrus has been deployed to contain the situation. Hans' wife Hanna assumes control and contacts Cyrus, explaining the trio were developed specifically for use against civilian populations. She instructs him to observe and report on their performance but not to engage with them.

The trio kills numerous residents of the trailer park and Celeste is wounded while protecting Daisy from Cockroach. Vietnam veteran Josiah shoots Cockroach, and the trio regroups and cuts the electricity to the park. Daisy, Celeste, and Josiah hide in the trailer of police officer Kovacks but Josiah is injured by Cockroach. Butcher finds photos of himself with Celeste during their military services. Kovacks is chased to his cruiser by Cockroach, who is fatally shot by Celeste. Celeste and Daisy get into the cruiser and leave the unconscious Josiah behind. Crybaby bursts through the passenger seat and repeatedly stabs Kovacks, who shoots him and drives into a dumpster, killing them both. Celeste retrieves Cockroach's chainsaw and confronts Butcher, armed with a meat cleaver and fire axe. Butcher lowers his balaclava, revealing his identity to Celeste and reminding her of his vendetta. They charge each other and Celeste severs his leg with the chainsaw, then kills him.

Cyrus approaches Celeste, Daisy, and Josiah afterwards and offers to relocate them in exchange for their silence. Hanna tells Cyrus she considers the ordeal a successful demonstration of the super soldiers' capabilities and orders him to keep the survivors under observation.
