Ming is seeking the Jewels of Power, but a female archeologist named Atuskedero is also after them and travels to Tibet with Lothar and Mandrake (the latter worked with her in his pre-Defender days) to find the Jewels before Ming's forces do. But, when the trio discover the Jewels, it becomes clear that they have the power to hypnotise anyone who touches them. Can the remaining six Defenders reach their two companions in time to prevent an ancient legend - which predicts that the Dragon of Vengeance will appear if the Jewels are ever disturbed - from coming true?
