Hidden Narcotics

Follow Border Patrol's Air Mobile Unit as agents track suspected illegal immigrants through the mountains - with the added cargo of three apprehended illegal immigrants from the previous shift. When they catch up with a group of border crossers, agents discover a possible gang member among them. Later, officers stage a sting operation to infiltrate a human smuggling organization, and uncover hidden narcotics inside a car passing through the busiest land border crossing in the world.
