Tony Stark, CEO of a major weapon factory, physicist, engineer, and brilliant inventor, gets injured by shrapnel from one of his own weapons. While being kept hostage by terrorists, he creates the Iron Man Suit and flees. From then on, he swears not to squander his second opportunity at life and to use it to make the world a better place. He travels to Japan for this reason. Great steps have been made in Japan's Lab 23 to design and build the Arc Plant, a one-of-a-kind power station that does not use fossil fuels. Stark desires to participate in this initiative, and in order to do so, he is ready to declare his retirement as Iron Man. At the same time, he will reveal the Mass-produced Iron Men.
