124 million people enter the US through its airports each year, a number that also involves an endless stream of contraband. Putting a stop to this, and protecting the borders, are the eagle-eyed Department of Homeland Security (DHS).

Watch To Catch a Smuggler on National Geographic, Fridays at 9pm, to see how DHS ensure the safety of all citizens and law-abiding voyagers crossing the borders.
