In the South American island state of San Cristos a puzzling disease is rife. The respiratory tract of the babies and toddlers is stricken with a virus that leads to their death after a few days. The researchers suspect a Diphtheria vaccine, which the USA government sent to the developing country, was the triggering factor. Reason enough for the reactionary opposition led by Boutillier to begin a virulent campaign against prime minister De Ville. He searches the progress for his country to be in contact with the industrial nations. Quincy and Sam fly to the crisis area to probe the suspicion against the American drug. According to the first investigations the vaccine can be excluded as a cause. However, a further research is prevented by religious regulations, since every corpse may be released only after a dead person's wake of 24 hour until the autopsy. However, not only the religion is obstructing Quincy, local politicians blame the drug for endangering the lives of numerous children.
