Synopsis
Banner hides out in Tony Stark's mansion , where the Iron Man has a secret government project going on, to build and test a new armor, capable of resisting gamma rays, and possible future terrorist threats.
After Dr Banner is wrongfully attacked in his room (actually Tony's) , mistaken by the attacker, Richard Cummings(who claims his sister Lisa's suicide was Tony's fault), now kept prisoner in the mansion , Banner agrees to keep secrecy about that and also agrees to help Stark and his partner, Jack Rutledge, in the development of the new suit.
But the deadlines are overwhelming
Banner and Rutledge insist that Stark's shoulder injury (caused by Cummings) makes the research too dangerous. But Stark insists that the final test takes place as it was planned, and he is going to wear the armored suit.
Meanwhile, Cummings gets free , taking a guard's uniform, swearing revenge against Stark, even if he's got to kill Dr Banner and Rutledge
