From the port of Buenaventura--the most dangerous city in Colombia--three men embark on a journey over the dark murky waters of the Pacific. A set of mysterious coordinates is their guide, a fishing net is their cover, and a narco-torpedo filled with 100kg of cocaine is their cargo. Following estranged brothers as they risk everything for a chance at a better life, Manos Sucias takes a close look at life at the bottom of the food chain in the international drug trade.
