Tony Stark (Robert Downey Jr.) is the CEO of Stark Industries which produces advance weapon systems for the U.S. military. Tony’s father started the company after WWII, and after his death Tony inherited the company, worth billions.

Tony lives the life as a hard drinking, rich playboy ladies man, but he is also a genius who has invented many high-tech items for the company. Tony flies to Afghanistan to demonstrate a new weapons test to the army. On his way back to his plane, his convoy is attacked by terrorists, and Tony is wounded by a Stark Industries missile. Tony is captured and held hostage in a cave with Raza (Faran Tahir), a doctor who saves his life. The terrorists force Tony and Raza to reproduce the new destructive Jericho missile Tony was demonstrating from parts of other weapons. Instead, Tony decides to build a suit of armor with Razas help.

The suit gives Tony the strength and protection to be able to escape the terrorists. Back in America, Tony builds a better suit of armor which gives him superhuman strength with the ability to fly. With the help of his personal assistant Pepper Potts (Gwyneth Paltrow) and Jim Rhodes (Terrence Howard), Tony vows to protect the world as Iron Man. Douglas Young (the-movie-guy).
