Georges Polti develops the idea that a limited number of fundamental situations can generate an infinite variety of stories. He identifies thirty-six of them, each defined by specific forces, roles, and tensions: revenge, rivalry, sacrifice, pursuit, supplication, family conflict, and more. Drawing on examples from theatre, novels, folktales, and history, he shows how these situations can be varied, combined, and transformed. The book therefore offers both a framework for understanding human passions and a valuable reservoir of dramatic structures for writing novels, plays, or screenplays.
