The film's plot is based on the
Kennedy assassination and subsequent investigation. The film begins with the assassination of President Marc Jarry, who is about to be inaugurated for a second six-year term of office. Henri Volney, state attorney and member of the commission charged with investigating the assassination (based on the
Warren Commission) refuses to agree to the commission's final findings. According to the commission's rules, the member who refuses to go along with the conclusion of the investigation is tasked with re-investigating the assassination. Volney and his staff subsequently find many discrepancies in the official story, eventually uncovering a conspiracy between organized crime and the country's intelligence agency to assassinate president Jarry, that leads to Volney's murder himself. ==Fictional state==
