There is a mixture of moving parts in this film. It feels scientific due to  labs and experiments. There is also a component of poverty since there is a trailer park with many residents trying to make ends meet. On top of that, there is a small war in the works. Onslaught is directed by Adam Wingard who creates a desert setting filled with all kinds of vengeance. The dystopian direction is surreal. Yet in the midst of the chaos, Onslaught had me puzzled.

The rogue squad is controlled by an evil doctor named Hans Kammler (played by Dan Stevens), He brings soldiers back to life to do damage. His love is Hanna Kammler (Rebecca Hall), and she supports his bizarre vision. He engineers soldiers to cause damage for his satisfaction. The one caught in the middle is a young sniper, Celeste (Adria Arjona). Celeste’s main priority is her daughter Daisy (Blake Kennedy). With danger all around, she must put her efforts into stopping the soldiers from attacking her and her daughter. 

This film is an end-of-the-world thriller on acid. The resources continue to multiply and become more deadly. A detective, Cyrus (Drew Starkey), comes on board to try to identify the appropriate solutions to the explosive matters. He follows the steps where the deadly soldiers leave their marks. He also follows the trail of Hans Kammler. With Hans and Hanna as the enemies, there is a possessive state-of-mind that overcomes the characters.

Onslaught is different from most thrillers because the scientific scenes are featured more than the treacherous moments at the start of the film. I found this foundation appealing since it  created an understanding of what resources are risky to the plot of the film. There is no easy way to define the outcomes. Overall, the thrilling vibes are endless making Onslaught vivid and engrossing.

The film fits the definition of psychological suspense and offers an ample dose of adrenaline in the heart of the desert. It is a ninety-minute ride of unforgettable vengeance. Three-and-a-half out of four stars for Onslaught.
