Embark on a bloody journey from Los Angeles to Juarez as lawlessness of the Old West is brought to the present. Welcome to the new Wild West.

The story ignites when the ruthless and rapidly rising Mendoza Cartel bombs the DEA's offices in Los Angeles, killing seven agents in a brazen act of terror. Determined to strike back, the Deputy Attorney General orders the creation of an interagency task force to bring the cartel to justice. The team is an uneasy alliance of three very different lawmen: hardened LAPD detective Ben McCall, sharp FBI agent Kim Evans, and gambling-prone DEA agent Eddie Guerra. They soon learn that an FBI agent slain in the bombing had been investigating the sale of military-grade weapons to the cartel. As the trio tear through the cartel's street operations, each carries their own secrets and hidden agendas, and their pursuit of the truth threatens to pull them apart as surely as it draws them toward their quarry.
