Fog of War

Working the varied terrain of San Diego, California are officers and agents of the Department of Homeland Security; men and women dedicated to their duty of defending the United States busiest border crossing. Three components of U.S. Customs and Border Protection watch over this 66-mile stretch of the border and beyond from the air, on the ground, and at the ports of entry. Their mission is to secure the border against smuggling of contraband and unlawful entry into the U.S. In this episode of Border Wars, officers and agents in San Diego discover thirty people elaborately concealed in a tractor-trailer, race to prevent people from illegally crossing the border under the cover of a blinding fog, and unearth a payload of hundreds of pounds of marijuana carefully hidden behind the cab of a tractor-trailer.
