Tony Stark is finally at Congress to tell them about the abilities of his Iron Man armor, after it's been put off for the last ten issues or so. As Tony starts to speak, he suddenly collapses as his chest plate starts malfunctioning. Although some members of Congress are skeptical and think that he's only pretending to be sick since he didn't want to testify for months, a doctor is found, and confirms that Tony's heart is injured. Tony is taken to hospital, which is reported over the radios, and heard by Pepper Potts and Happy Hogan. Being the only person to know who Iron Man is, Happy wonders whether he should say anything.
After a few days in hospital, Tony's chest plate has been recharged by the doctors, who suspected that it was to help his heart. Tony is well enough for the press to interview him, who ask whether Tony is Iron Man. Tony denies it, even though he was ready to admit it before Congress. He decides that he had the heart attack just as he was going to tell them of his dual identity due to fate not wanting him to reveal his identity. However, people are still speculating that Tony could be Iron Man.
A few days later, Iron Man is spotted by some teenagers, who mention that Tony Stark can't be Iron Man, since he's still in hospital. Iron Man then keeps flying around, albeit clumsily, and when he reaches Tony Stark's hospital, he takes off the armor to reveal himself as Happy Hogan, who put on the armor so that people wouldn't guess Tony's secret, and goes to return the armor to Tony. However, this meeting is viewed by the Mandarin from miles away, who doesn't hear what they're saying, and thinks that Happy is Iron Man. He then activates his teleporter and teleports Happy to his castle. Tony realizes that the Mandarin must be behind Happy's disappearance, and that it's up to him to save him.
After getting rid of Namor in Tales to Astonish #82, Tony Stark has decided that he will appear before Congress and give them a talk about the Iron Man armour, even if it means he has to reveal his secret identity. After packing away his armour in his briefcase, Tony starts thinking about whether it would really make that much difference if the world knew he was Iron Man. Upon leaving his factory, Tony bumps into some policemen, who tell him that he has to appear before Congress in Washington or else be taken to jail. Tony agrees to go to Congress, and gets in their car so that he can be taken to the airport. When he arrives at the airport, Tony changes into Iron Man, and then starts flying towards Washington. On the way, several radio reports are given that Tony Stark has finally agreed to appear before Congress, and that Iron Man is heading towards Washington.
Several of these reports are heard over in Russia, and a scientist who hears this thinks of what perfect timing it is, as Russia can redeem itself for having Iron Man defeat their champion, Titanium Man, months ago. Whilst he is thinking of this, other scientists in the lab around him are improving the Titanium Man armour. To test it, they fire a miniaturised rocket at Titanium Man, which has no effect on him. Titanium Man is then placed in a rocket, and launched to go fight Iron Man once more. Titanium Man's rocket reaches Iron Man just as he's approaching Washington. Titanium Man then smashes his way out of his rocket, and then goes to attack Iron Man.
