Operación Marea Negra plot
The true story of the people who made a 26-day Atlantic crossing in a homemade submarine carrying a load of more than three thousand kilos of cocaine. The boat was intercepted off the coast of Galicia, and the cargo was discovered. The boat was manned by, among others, Agustín Álvarez, a former Spanish amateur boxer. On board it was a matter of survival, because of storms, unpredictable currents, hunger, infighting and the authorities.
