In a joint project with The New York Times , FRONTLINE/WORLD correspondent Lowell Bergman investigates the business of human smuggling across the busy ports of entry between Mexico and the United States. In Tijuana, masses of people attempt to cross illegally every day with the help of increasingly organized and expensive smugglers. Bergman explores the region to find that this illicit but lucrative business is expanding, and U.S. border agents are subject to an increased risk of corruption. He follows the dramatic story of one such corrupt U.S. border guard, the risky business he became involved in and what the U.S. government is doing about the problem.
