Billionaire industrialist Tony Stark is using his advanced technology to restore China's ancient past by raising a sunken city to the surface. However, fanatics known as the Jade Dragons strenuously object to his activities believing he is violating the sacred city. Attacking the tech site, the Jade Dragons also kidnap the supervisor, Jim Rhodes and Tony's friend.
Worried over Rhodey's kidnapping, Tony flies out to take charge and is severely wounded by soldiers of the Jade Dragons and captured himself. The Dragons demand that Tony construct a weapon to rebury the city and Tony agrees. However, he tricks his captors and improvises a suit of makeshift armor that he uses to free himself and Rhodey.
Tony belatedly discovers that by unearthing the city, he has unleashed a three thousand year old tyrant, the worst of China's rulers known as the Mandarin. To save the world, Tony must unleash his greatest creations; armored battlesuits to defeat this ancient supernatural evil as the Invincible Iron Man!
