"Carlos" tells the story of Ilich Ramírez Sánchez who, for two decades, was one of the most wanted terrorists on the planet. Between 1974, in London, where he tried to assassinate a British businessman; and 1994, when he was arrested in Khartoum, he lived several lives under various pseudonyms, weaving his way through the complexities of international politics of the period. Who was Carlos? How did his various multi-layered identities fit together? Who was he before engaging body and soul in a never-ending struggle? The drama is built around these questions.
