3x11 - Hercules: The Legendary Journeys

King Orestes, Iolaus' cousin and identical look-alike, hoped to establish a League of Nations to bring peace to all the kingdoms in the area. But King Xenon of Garantus had other plans. His assissin killed Orestes, and Iolaus assumed his cousins identity to see the peace plan through. Thrust back into Queen Niobe's life, Iolaus and the young widow consummated their love for each other. But Xenon set Iolaus up for attempted murder and planned to slay the other kings. With Niobe's help, Iolaus foiled Xenon's plans and cleared the way for Niobe to continue her quest for peace.
