Sal Martinez was a drug agent who did everything by the book. Which means he broke the laws the Feds wanted him to break...'Go down there and sell some drugs. Bust some heads. Play like a mafioso.' Then one day Sak crossed the line - and he's still paying for it. Bowden studies the life of career DEA agent, Sal Martinez as he prepares to go to prison for 87 months. Martinez worked on both sides of the Mexican boarder for seven years in the DEA. Most of Martinez's work was undocumented, allowing him to carry out assignments with at his own discretion. That often meant the use of Mexican police tactics. It was these same tactics that the FBI say Martinez asked the police to use on a young man who killed his cousin. Bowden takes a look at Martinez's unusual case. "Normally, an agent who crosses the like Sal did gets sent to a shrink or tossed out of the agency. Not sent to jail."
