The famous weapons designer and billionaire (Tony Stark) lives a noisy life. He is kidnapped by an extremist group to design a nuclear weapon for them, but he designs an iron suit that resembles a protective shield, and wears it to protect him during his escape. He succeeds in escaping and returns to America. His life has completely changed, and he stops trading in weapons, but he is surprised that his assistant and his father's friend (Opadia) sells weapons to extremists, so he decides to wear the Iron Man suit again to recover the weapons.
