Desc: NarcoSubmarinos: Directed by Jaime Escallon-Buraglia. Home-built submarines trying to smuggle large amounts of cocaine to the U.S. are detected every day across the Pacific. From the FARC - controlled jungles in Colombia, where the vessels are built, to Mexico's Pacific Coast, where the Sinaloa Cartel awaits for the arrival of the cocaine-packed submarine, the documentary unveils a risky and ingenious form of smuggling.
