The story of two great civilisations, the Trojans and the Greeks/Spartans, led by two men, Paris and Agamemnon, who battled for ten years over the love of one woman, Helen of Troy. Helen's astonishing beauty caused her father Tyndareus, the king of Sparta, to keep her prisoner in her own home, terrified that other men's desire to possess her godlike beauty would destroy his kingdom. Helen was allowed to be seen in public only after her father had arranged her marriage to Menelaus, the man who was to succeed him as king. Agamemnon, Menelaus' older brother and the husband of Helen's sister, was so enamored of Helen that he made every Greek/Spartan warrior take an oath that no man in the kingdom could ever touch Helen: if he could not have her, no man would. But one young warrior, Paris of Troy, knew nothing of the oath, and his encounter with Helen would change the course of history.
