Parasite Zero.

Three U.S. federal agents along with a squad of Mexican federales are pulled into a seek-and-find mission for a synthetic toxin created in the Baja California Peninsula.

The team discovers that the drug cartel is actually manufacturing lethal parasites — a drug that infects peaceful citizens and turns them into homicidal maniacs.

The DEA agents and local police officers must band together and fight for their lives as they find themselves trapped in a village where every living being is contaminated by the substance.
