Cowboy Cartel is a four-part documentary series featuring the remarkable story of a rookie FBI agent. Scott Lawson cracked the case of one of Mexico’s most ruthless cartels, Los Zetas and the multimillion-dollar money laundering operation they ran through the heart of the American Quarter Horse racing industry.

The documentary is an unbelievable true story of an unlikely hero from rural Tennessee. Lawson’s investigation took down the Treviño brothers, the leaders of Los Zetas, one of the most powerful cartels in Mexico. While the Treviños terrorized thousands in their pursuit of power, money and influence, Lawson risked his life on a hunch.

He tracked the brother’s racehorse transactions in the United States, infiltrating the deadly cartel and uncovering their international money laundering operations.

Cowboy Cartel features first-time interviews with FBI agent Scott Lawson, who broke the case; IRS agent Steve Pennington; Irving police officers Steve Junker, Brian Schutt and Kim Williams; Assistant United States Attorney Doug Gardner; Pulitzer Prize-winning New York Times journalist Ginger Thompson; and Joe Tone, the author of “Bones: Brothers, Horses, Cartels, and the Borderland Dream,” among many others. 

Clearly, Apple TV continues to expand its nonfiction programming, adding Cowboy Cartel to the list, which includes The Dynasty New England Patriots, Messi’s World Cup: The Rise of a Legend and Stephen Curry: Underrated.
