In the shadowy world of international espionage, a group of former intelligence operatives, now masterless "ronin," are assembled for a single, high-stakes mission. Hired by the enigmatic Natascha McElhone, the team includes the coolly analytical American Sam, played by Robert De Niro, and the pragmatic Frenchman Vincent, portrayed by Jean Reno. Their objective is to intercept a mysterious, heavily guarded briefcase whose contents are unknown but desired by ruthless factions across Europe. As the mission unfolds in the gritty streets of Paris and Nice, directed with precision by John Frankenheimer, alliances fracture and trust evaporates. This tense, cerebral drama pits these skilled professionals against not only lethal adversaries but also their own hidden agendas, creating a labyrinth of deception where every move could be their last.
