The Gatekeepers

A joint venture between Discovery and BBC Studios, offering unprecedented access to the Department of Homeland Security (DHS) Customs and Border Protection agency as they operate on the 28 bridges connecting the United States of America and Mexico. The lives and work of the DHS are followed and explored as they guard the border and process the millions of people who cross it every year, as well as finding a wide array of illegal contraband, much of it expertly concealed.
