This is the true story of how El Chapo built the world's wealthiest and most powerful drug-trafficking operation, based on months' worth of trial testimony and dozens of interviews with cartel gunmen, Mexican journalists and political figures, Chapo's family members, and the DEA agents who brought him down. Over the course of three decades, El Chapo was responsible for smuggling hundreds of tons of cocaine, marijuana, heroin, meth, and fentanyl around the world, becoming in the process the most celebrated and reviled drug lord since Pablo Escobar. El Chapo waged ruthless wars against his rivals and former allies, plunging vast areas of Mexico into unprecedented levels of violence, even as many in his home state of Sinaloa continued to view him as a hero.
