From the darkness of his headquarters, Mr. Karbo Vantas, a former cattle rustler and now director of the International Vantas Agency for the fight against crime and evil, recalls his most famous cases into an old tape recorder. The International Vantas Agency is formed by a bunch of anonymous heroes gifted with parapsychic abilities. In “The Frightening Case of the Mortal Pigment”, two Vantas agents (sophisticated Valechka Faruk and relentless Wallace Almeida) have to cope with two perfectly ludicrous villains (Gonzalo Delamarr and Julio Filardi) and a mystic serial killer (mad artist Bruno Lotti). The U.F.O. enthusiast journalist J.J. Bélmez follows the proceedings misunderstanding everything but his love for Valechka. The coming of real alien spaceships only serves to thicken the plot.
