Robert Wise directs this swords and sandals epic. Young Trojan Prince Paris (Jacques Sernas) journeys to Sparta hoping to negotiate a peace treaty to end the war between Troy and Greece. Washed ashore following a storm, Paris meets the beautiful Helen (Rossana Podesta) and unaware that she is the Queen of Sparta, falls in love with her. When the Spartan King Menelaus (Niall MacGinnis) recognises that the pair are lovers Paris flees to Troy, taking Helen with him. Paris' actions make matters worse for the Trojans: the feuding Greeks unite and are determined to avenge the insult to Menelaus. Laying siege to Troy, the Greeks led by Achilles (Stanley Baker) devise a unique plan to gain access to the city and destroy their enemies.
