Two brothers from Colombia, Salvadore and Raul San Martin, are operatives with World Designs Ltd., an organization that meddles internationally in the name of justice, freedom and equality, and whatever else might catch their attention. Salvadore and Raul have been assigned to work for the Argentina Gendarmeria Nacional as a part of an elite unit involved in enforcement against illegal drug trafficking. This unit targets the top level drug lords that arrange for vast amounts of cocaine to be harvested, transported and distributed across international borders. Drug lord Ramon Subizar is planning a major drug push on Christmas eve at the borders of Argentina, Brazil and Paraguay. But the Gendarmeria intend to crash Subizar"s party. Add to the brew a volatile horse called Don Diego, a Buell motorcycle, a gypsy aeroplane pilot, and the drug lord with his new product of opium, and there is guaranteed to be an explosion.
