In a serene coastal town, a series of unusual and gruesome deaths start to puzzle the local community. Sheriff Richard Tarbell finds himself overwhelmed as the normally quiet town becomes increasingly fraught with panic. He teams up with Elizabeth Johnson, a scientist who arrives to investigate the strange occurrences. They soon discover that genetically-engineered, flesh-eating cockroaches are the horrifying cause of the mounting body count. These mutant insects, originally designed for pest control by a local corporation, have mutated beyond anyone's control, turning into deadly predators that can consume anything in their path.

As they delve deeper into the mystery, the town’s history of secrecy and corporate greed unravels, revealing the corporation's unethical experiments. The infestation escalates, causing widespread chaos and showcasing the insects' horrifyingly effective adaptations. The tension crescendos as Tarbell and Johnson race against time, attempting to find a way to stop the ruthless creatures before the town—and possibly the world—succumbs to the swarm. What started as a small local concern has turned into a ticking time bomb, and the stakes have never been higher.
