Operation Condor was a cruel campaign of political repression and state terror involving military operations, dictatorships, and assassination throughout South America. In the country of Uruguay, it imposed an authoritarian government dedicated to the capture, jailing, torture, and killing of all opposition. Thousands of workers, students, dissidents, and politicians were prosecuted and eliminated. The bloodshed was horrendous. Others were kidnapped, tortured, and killed in allied countries, or illegally transferred to their home countries to be executed following Condor operations. Then in Uruguay, a young medical student, Daniel Blum, distraught by the kidnapping and murder of his beloved girlfriend, and seeking revenge, conceives a risky plan to find the assassins. Oblivious to the danger, he enters the morgue claiming an interest in forensic medicine where, between corpses and autopsies, he succeeds in befriending some of the detectives, winning their trust, which allows him to enter the main police center. He succeeds in obtaining training in the use of firearms, but he finds himself powerless and unable to advance. He then manages to help a friend to escape capture by the dictatorship and this draws him into a secret underground organization. Using newfound resources and alliances he works to solve the murder of his girlfriend and the kidnappings and murders of other young students. Then he meets a young woman who becomes his companion and lover. With her at his side, he attempts to solve these mysterious murders while avoiding being crushed between the powerful opposing forces of the dictatorship and the opposition.
