In the 1930s, charismatic Dominican diplomat and playboy Porfirio Rubirosa (Manolo Cardona) navigates high society, espionage, and political danger during the rise of dictator Rafael Leónidas Trujillo (Damián Alcázar). As Rubirosa infiltrates Trujillo's inner circle—even marrying the dictator's daughter, Flor de Oro (Carolina Guerra)—he uses his charm, intelligence, and romantic liaisons to covertly assist opposition forces while managing a high-stakes double life among the international elite.
